RTV was not bad. Now the channel is wasting space running stupid annoying infomercials all the time. What is the point of a channel that runs infomercials all the time. Just a big waste of space. I hope they stay in Connecticut and not move to the ESB wasting power showing useless infomercials on there since they are cramped for space.

RTV was not up to the standards set by WSAH. I won't get into specifics, but let's just say that when someone in charge at WSAH calls to complain about pressing problems (like ads that were sold and then not shown), getting yelled at by the people at RTV did not leave a very good taste in their mouth.

The infomercials make them more money than RTV did.

I've heard unofficially that RTV is seeking another affiliate in New York, but nothing beyond that.

MeTV is not a network.

This TV, I've heard nothing about with regard to New York, but I have to imagine it will pop up soon. New York is a glaring hole in the network's coverage and would easily put it over carriage in 80% of the country.

trip i read about the problems with rtv, on another site, seems like those technical glitches are not being corrected, on other rtv affiliates either imho think it would behoof the connecticut region if wsha would broadcast wfsb or wtic, on wsah sub channel.
just my cents.

I understand stations need to make money. But that's not our problem as watchers. We know stations claim to serve us but really serve those who pay for commercial airtime.

It is a matter that we want quality programming more than informercials. So, WSAH had a good reason to get rid of Retro-TV, that doesn't mean we like it.

There are so many millions with OTA now. Money is tight in this economy. Why can't the networks put up what people want to see

1) 24/7 news like CNN
2) 24/7 movie station or THIS TV RTV, ME TV
3) A station like A&E, Discovery channel, ect ( How hard can it be to make a DOG the Bounty Hunter type shows. Or Kate plus 8 ect.

4) Channel 21 with a link for NYC

5) ESPN

6) TNT type of channel

7) Free PLAYBOY channel (A man can wish no?)

Just saying with over 50 million OTa people (anyone know the actual number?)

The Networks have a niche market. The cable company's are not involved with OTA. So Instead of the networks complaining about losing share. Make OTA like a mini FREE Cable network. Compete with the cable companys like they do with the networks.

This can not be hard to understand for the networks

I agree, and frankly just don't understand why the networks are jerking around!

Firstly, what are the actual limits (comfortably, without compromising quality) with digital OTA transmission?
For instance, is it possible to simultaneously transmit:
(1) 1080 HD and (1) 720 HD, and (1) 480 SD, -OR-
(2) 720 HD and (2) 480 SD sub ch's. -OR-
(1) 720 HD and (3) 480 SD subs -OR-
(5) 480 SD ch's?

Or is all of that entirely too optimistic?
Regardless...

It would seem the networks are currently in a very good position to go to war with cable/sat providers, up the programming choices, and give the consumer a real alternative to paid TV - and they would get to keep all the advertising dollars.

I think the question that must be answered, and is really the determining factor, is: How does the money flow???

The way I understand it, cable/sat providers get paid from the subscriber and from the network to carry their programming. But the major networks also produce many shows shown on the cable/sat networks, new and exclusive in addition to what's in syndication. (For example, CBS produces "The Guardian" on Sleuth network.)

So currently networks would theoretically have to pay extra to have the cable/sat providers carry their sub channel transmissions, yes? (If CBS put "The Guardian" on a sub channel, etc.)

Better still, why can't the networks just act like a cable/sat provider and lease their extra channel space to the same networks that are already on cable/sat? TNT is on cable, Dish & Direct TV... Why not on CBS's OTA -2 transmission also? NBC can cut a deal with USA, and put CNBC on a SD sub, etc, etc... THEN WE'D HAVE A REAL ALTERNATIVE TO PAY TV!

Of course the masses would first need to be educated that the OTA HD quality is superior, and that (for the most part) they don't need the 10'x14' yagi monster antennas of old on their roof.

Problem is, the moment the cable/sat providers realize they're losing revenue due to people dropping their service they will change their tune and cut a deal with the networks, and in the end we will all get screwed...

And I also agree you're smoking some good sh!t if you think we're ever going to see free OTA Playboy! :D LOL!

As much as people would enjoy the major networks shooting themselves in the head, I sincerely doubt it will happen.

Cable networks receive money from cable systems, not the other way around. Every person who leaves cable/satellite for OTA is a loss of a guaranteed fee in favor of the chance of slightly better ad revenue in a bad ad market.

Since all of the major networks are co-owned with many cable networks, many more so than will ever be available OTA, none will go this route.

See this is how I originally thought it went - but then I got misinformed.:o
So TNT for instance is getting revenue from Dish, Direct, and all the cable co's also. So then, yes why would they want to pay to be carried on an OTA network's sub channel...

And then so also are the OTA networks paid by the cable/sat providers to be carried on their systems? And if the OTA networks try to become the competition it will be a war, and the cable/sat providers will stop carrying the OTA networks?

So who is getting the ad revenue from commercials on a cable/sat network - the cable/sat provider, yes?

Then can it be looked at from another angle - would it be cost effective for the OTA networks to pay the cable/sat network (and if it's co-owned all the better) to be on their OTA subs? And by default, so to speak, gaining viewership from those that cancel cable/sat, reaping the ad revenue, while saving on not having to produce extra programming to fill these slots?

I'm just looking for a way to justify a win for us little guys here!
I am finding it ridiculous to have to pay almost $100/mo to watch TV - WITH COMMERCIALS!
The cable/sat companies need to be brought down a few notches, and this can now be done with digital OTA - I have read that 98% of this country can receive OTA reliably with the right equipment.

If someone will just have the balls to throw the first punch. :D

CBS has decided that pristine picture quality is preferable to additional subchannels. Given the current state of the advertising market, I don't think I disagree.

Also, the viewership of the sub-channels is below minimum standards to have ratings published.

We have very much of a Catch 22 situation.

Carriage makes programming available to the audience.

Programming attracts viewers.

Viewers mean ratings. Ratings equal advertisers. Higher ratings, higher ad rates.

Programming costs money.

Today, stations are cutting budgets.

The circle goes round and round!

I'm OTA here 40 miles north of NYC. CBS-2 is to be commended for no sub channels. ABC by comparison looks like crap, and no, it's not the 720 vs. 1080 issue, its the bitrate and the way ABC starves .1 to feed .2 "lifestyle" channel. These subchannels are a waste. I don't even bother to program them into the system. Much like my Dish setup, where I have a favorites list and that's pretty much it-I have little enough time as it is to waste it on watching "shopping channels".

How did you come about obtaining the spool.

If there are any ham radio guys on line here they love to have it.

You can use use the coax for tv signals but you must match it to 75 ohms. The ham radio guys do it all the time when they build a long wire antenna that is at 300 ohms. I have seen the directions to do it. I do not know just where. All coax has the lowest loss when new. As moisture corrodes the shield & the foam breaks down then the loss goes up just like 300 ohm. Many ham radio guys still use 300 ohm because 300 ohm wire loss is really lower than coax. But a lot of of extra care is needed to mount the 300 ohm wire that the coax doesnot. If they still manufactured 300 ohm open wire it would be the best of all. But where do you get it today. It had the lowest loss of all. You can make it buying #12 bare solid copper wire. But you would have to cut pvc pipe into spacers & drill holes to build the 300 ohm open wire. But is great because the loss does not go up as it gets old. You could run the 300 ohm open wire from the antenna down to a good location to a preamp or amp. Then from the amp to the tv can be 75 ohm coax.

Yes, I'm a ham and I have a length of LMR 400 feeding a UHF/VHF discone on the roof. It's overkill for UHF and VHF, but for 800 mhz signals, there is a difference. My OTA TV system has RG-6 from the Cable Company, mostly, and I get all channels well except channel 50, which is a bit over 500 mhz. This is also due to the fact I split the signal four ways without an amp. I have a large antenna, and this with no amp, which I could not use as my ham radios would cause havoc. Now I can transmit and not bother TV.

Sell the LMR 400 to another ham and buy better RG-6, fresh connectors and splitters (I had one old splitter causing no end of problems till found). The 400 is expensive !

I wonder if ladder line would work at these frequencies. Even if it did, it would be a royal PIA to run compared to coax. Hams used ladder line because it has low line loss when transmitting at high SWR, which is not relevant for a receive - TV setup. (hams also must use a tuner with this setup)

it was a corporate decision for cbs owned and operated stations to not have subschannels. do u really want cbs to sacrafise picture quality for awful subchannels with weather or other usless programming?

a lot of networks are experiemnting with subchannels but no one has yet to make a profit from it. in new york, weather plus on nbc failed. now that its replaced with new york non stop programming is not much better and no one is watching. the tube previously on wpix's subchannel failed and went out of business. abc hd looks like crap because they gave bandwith to live well hd that no one watches. all these channels are buried on the cable dial and handful of OTA viewers are watching these because their viewing options are much more limited.

in very small markets where there are cbs affiliates (not owned by cbs) the subchannel may be a less popular network with no affiliation in that market such as CW or MyNetwork, weather, or informercials.

i have no prob with one main channel in HD and 1 or 2 subs in SD. the problem is the network's lack of will to create a good sub-channel. someone said the Weather sub-channel flopped.... no shite.... of course it did. it sucked! and NY-Non-Stop sucks almost as much! i hope it gets shaken up a bit.

i'm sure WLIW-21 viewers are damn glad to have PBS World as a sub! and the cost to air it cant be exorbitant since those shows are not exclusive to PBS World. they have been shown on PBS before. i wish i could receive WLIW-21 with my gigantic antenna in the kitchen! :(

NBC, CBS, ABC do not have to create brand-new programming to fill their subs. they just need to have commom sense and good taste to pick some oldies that ppl want to see. the current economy doesnt help, i know. but they are wasting their bandwidth anyway with their current subs. they should just run old shows for which they hold the rights. even stuff from the 60's would get ppl to tune in, i believe.

i have my PC hooked to my 37" LCD so i can watch LOTS of full TV episodes (a few in HD, mind you) from Hulu and YouTube. i watch Outer Limits, Star Trek, Daily Show, A Team, etc, etc. at my home, the 'Net is compensating for the fact OTA programming sucks.

I see no reason whatsoever to manufacture sub-channels where none are needed. I also don't see then need to make an "SD" sub of the main HD-1 channel. Let the converter box take care of formatting. Why else would you need an SD sub for the same content?

A useful sub-channel for OTA might be time-shifting the main HD-1 carrier by three hours or so (even less) for someone to catch something at a more convenient time without having to resort to a hard drive setup. I'm not sure how program licensing issues would work or not work in that scenario, however.

But in the absence of a necessity for sub-channels, I applaud CBS for giving all the bandwidth possible to the main signal.

Like I said before channel 11 is watchable now since I expanded one of my dipole antennas all the way up. It even made channel 13 stronger while not making channel 7 any weaker. Channel 7 likes it when the dipoles are down.

As for subchannels channel 7 needs to get rid of that live well network or stop broadcasting in 720p. Channel 7 is the most watched network with the worst picture quality. Also it does not make no sense for channel 11 to have two spanish sub channels. Should those channels be on channel 41 which I can never get, channel 47 or channel 68.

Here is a link to an interesting article from the December 1962 issue of Popular Mechanics entitled "Here Comes UHF-TV!"

Although obviously dated, it compares VHF & UHF reception and illustrates different types of UHF antennas.

Interestingly, it talks about people needing to buy $30 converter boxes to enable their VHF-only TVs to receive UHF broadcasts.

There are many parallels to the government enforcement of the DTV conversion. Apparently, even a decade after UHF was introduced, TV set manufacturers did not include UHF receivers.

u are extremely naive to say just because WPIX's subchannels are spanish that they should be grouped with 41,47,or 68.

#1- LATV and Estrella are paying Tribune/WPIX to carry those subchannels. Tribune is having financial troubles and this helps their bottom line. Also gives those 2 channels exposure in the #1 DMA.

#2- The 2 channels compete with Telefutura, Univision, and Telemundo. Why would any say NBC owned Telemundo 47 want to carry a competing service on their subchannel?

There seems to be more Spanish programing then English now. I understand soon (next 10 or so years) The main language of USA will be Spanish.

programmers & networks will put on whatever they think the market wants/needs and will generate profit, not what lexus2108 prefers. on the cable dial there are something like 300 english channels and 30 spanish channels. on OTA the ratio of english to spanish channels is different because there is a greater # of latino households cannot afford cable.

Just learned that the FCC has approved WABC's application to install a backup transmission facility using its old analog antenna at 4TS.

The application was made just days ago. What I don't understand is that the station applied for its ESB, main facility to increase power from 11.69kW to 27.0kW - this application was made at the end of June. The Construction Permit still hasn't been granted and the status continues to be pending. I realize that the Commission has to study and determine the impact of increasing a station's power, but with all the problems so many viewers have had since the station ignorantly left UHF for V, one would think and hope that there would be a more timely response to the application.

It likely causes impermissible interference to WNJB-8 and so ABC would have been asked to modify the application either to eliminate the interference or to show an interference acceptance agreement.

What's so strange is that the Commission allowed WABC to use Channel 7 because the plan was for WNJB (8) to "co-locate" at 4TS this month. The station reneged, which then, in my opinion obviates WABC using Channel 7.

WABC should put all of us out of our misery and move back to UHF and be done with its crazed obsession with using Channel 7 - which by the way, goes all the way back to when Edward Noble founded ABC!

Have no idea when it will be fired up.

The back up is authorized only for Channel 7.

If the station eventually throws in the towel on VHF, it will first have
to select a UHF channel that can be used and file an application with the Commission.

One more time in regard to CBC2-1, most respondents are apparently HD wievers, and I have to agree with you gentlemen, as Trip put it, the one ch. does give pristine PQ compared to other TV subch., however, most users are catode/conv.boxTV OTA wievers for whom there is no difference in PQ of subch. therefore they would welcome more subch. the happy-go-lucky TVRemote scroll surfers.
Considering possibilities that 25% HD wievers count to produce 75% GNP, 1main ch. no subch. as ch.2CBC maintains would be beneficial to ch.2, but if the 25% HD users bring in 35-40% of GNP- GrossNationalProduct, then the 75% ovalTV/conv. box counting for 60-65% of GNP the happy-go surfing bored TV crowd spell troubles for the dinosaurs of CBS or any one ch. TV unless there is following.
The Nielsen ratings basically function on Andy Varhol quip of 15min. fame, if you see 15min of 1/2hr.-1hr sitcom, or 2-3hrs of entert.sport event, you have seen ad the advertisement-TV gurus want you to see to be exposed to.
The second most important matter in regard to infommercial is to be exposed to the ads, to see and hear it and hopefully in future to buy it, one main ch. gives less chance to see it than more sub ch. that is why we see one commercial on 2-3 stations same time.
Let's see what happens in future, seem to me there is not much future for 1ch only
unless existing programs rating equal the time of competitors ratings.Alo

That's quite an assumption you've made there. CBS is running full 1080 I with superior video, which is very obvious when viewing live sports events.


It may be true that there are certain areas where economics have limited the sales of modern HDTV's. However, you can't state with certainty that most viewers still receive HDTV signals with convertor boxes and NTSC CRT televisions. Go in to any store still selling TV's in the NY area and you'll be hard pressed to find CRT televisions for sale and those which are for sale are bottom priced units with limited appeal. The cost of LCD HDTV's continue to drop. I say, good for CBS who would rather provide a superior signal than 2 or more inferior signals with inferior programming.

Other than Jersey Public Television I find most of what is being broadcast over HD 2, 3 etc channels worthless. The novelty has worn off and as of yesterday all channels which #1, don't transmit English language programming (I speak only English and so it serves no purpose for me to have to scan through a dozen or so channels with no programming I can understand, so I've deleted those channels.) and HD2 channels which are only rebroadcasts of a group owners same market signals. IE; WNYW and WWOR's HD 2 channels. I've also deleted WNET's HD 2 channel. I have no young children at home any longer and to be honest I can't see the point of running children’s programming 24 hours a day, especially when the HD 1 also is airing children’s programming. At this point I have to ask, how many small children are watching WNET’s HD 2 between 9 PM & 5 AM?

From a friend who works for WNBC, I will pass this on to you. With HD signals being transmitted, many cable systems are now using OTA reception as the source for retransmission instead of fiber. What that means is that even for viewers who receive their signals over cable or satellite outlets, the video quality on channel 2 is superior to the competition.

The switch to upper VHF has been a mixed bag so far. In Fairfield County where I setup my parents' OTA unit, it has tremendously improved reception. ABC, Pix11, and Ch 13 now come in consistently, the UHF channels remain strong or better.

However, I just moved over the weekend to a new place in lower Westchester. My room on the second floor has no cable, just the first floor, and the upper vhf channels have been spotty, especially ABC and PIX. The only thing that worked was having the dipoles fully extended and in the "down" position. This gets in the way of the door however.

The only thing I can think of is buying a small table and sticking it next to the window, with a southern view, and putting the antenna there. The antenna is one of the Terk "Silver Sensor" style antennas. Almost all the NY UHF channels except WLIW 21 come in fine.

Any suggestions?

Is CW-11 ever going to boost there power? They should since so many can't get it. With a antenna like that you should have had no problems. You probably can't put it outdoors. I can't put no antenna's outdoors either. I can get CW-11 but it is the weakest after moving one of the dipoles all the way up.

Sounds like a plan, as a first step.

Amplified or unamplified version?
Reason I ask is an amp can sometimes make a difference even on short cable runs, if the noise in the amp is lower than the noise in your tuner you will be able to get a lock on a lower power signal.

Almost all the NY UHF channels except WLIW 21 come in fine.

WLIW is transmitting from Plainview, L.I. and chances are it may be too far off aim from the ESB (and too far away) for you to get. Go to tvfool.com to see the details of the signals available at your location. (Put in your exact address and antenna height for the most accurate report.)

If you want to try some thing to get ch 11 better then try this.

If you have a set of rabbit ears, pull out the rods to to aprox 13.75 inches from the tip of each rod to the center. The rods should be horizontal or like flat. The total from tip to tip should be 27.5 inches. Then move it around & turn it & see how well you get ch11. That should be aprox the exact wave of ch 11 on those rabbit ears. So you have it maxed for ch 11.

If you try that & it helps; I can give you other tips how to connect it & not lose the other channels, if you want.

Trip, no correction necessary, as usual, you're absolutely right!

First, the old analog, VHF Combiner, which had WNET as a tenant, is now being used by digital WNET along with WABC and WPIX.

Second, WNET's analog transmitter was reconfigured to digital.

One half of the transmitter was converted to digital operation before the transition while allowing the remaing half to continue to be operated at full power. After the transition, the other half of the transmitter was then converted.

We are in Queens and can not get WLIW at all.

ALL NYC towers come in at 80% and above

My aunt would really enjoy WLIW.

AND yes I tried the new C2 Clearstream antenna. No difference then the old one. So it went back to store.

If WLIW went to NYC then she would get it for sure.

We still do not know how much WLIW boosted power as other poster stated. If at all

According to Trip's compilation of FCC records:

WLIW applied for a increase in power on 6/23/08 - to go from 89.9kW up to 251kW.

From the files I found, as of yet, the FCC has not granted this request.

Therefore, if someone is enjoying better reception of the station, enjoy it for as long as it lasts, it's probably due to atmospheric conditions.

No. But it will give you about 4 or 5 db more signal with which to try to overcome any RF noise that you're dealing with. People with weak signals (fringe areas) might get more reliable reception, but I expect that people in strong signal areas who are dealing with severe multipath will have stronger reflected signals that continue to interfere with their stronger primary signals.

It actually works out closer to 4.5dB (4.46dB to be exact;))

Keeping in mind that a 3dB gain is doubling the power, I think this actually may make a significant difference - and certainly for all those that were on the cusp of the digital cliff when receiving WLIW, the increase should bring home a reliable solid lock for them.

Look at it this way, if you were comparing two different antennas and there was a 4.5dB difference in gain between them, don't you think that would equate to a significant difference in performance?

Sounds like she's got a whole building between her and WLIW, and if she can't pick up a reflected signal from her westerly facing window she's probably screwed.

Unless...

I bet if you built a Grey-Hoverman (or an mclapp 4-bay bowtie) without a reflector, on some PVC and put it on the roof aimed due east-west it would get all the UHF - both from the ESB & WLIW. (And probably then some) Then join it to her Terk indoors with a UVSJ,

so the Terk is getting her VHF from the ESB as it is now. shouldn't cost you $20 :)

Is anyone seeing a signal on channel 26? WRNN-LD filed a license app for a highly directional channel 26 signal. I'm wondering if it's simulcasting WRNN-48.

WOW that is a big antenna.

But that is not what I was talking about.

The antenna akahooper stated would be a good one to try. It will fit in the back of a closet or behind the curtain at the window.

How well did she receive ch 21 when it was analog?

Did it have any ghost in it or was it just snowy?

Pete Putman has a new article on hdtvexpert.com about his house calls to fix DTV reception. One visit was to the rooftop of a house in Wall, NJ.

http://www.hdtvexpert.com/pages_c/UpOnTheRoof.html

It's amazing to me to see the antennas that he's using in Wall, NJ to pick up NYC broadcasts. I'm actually just a few miles closer to Empire and I'm using Winegard's largest dual-band antenna (HD7698P) in my attic, and I was having so much trouble with WNET that I gave up and pulled it from my tuners' channel lists. Most other channels are acceptable, though. He's using two antennas that, combined, total up to far less boom length and similarly less gain, and he's picking up all of the stations that I'm struggling to receive. I just don't get it.

I really wish I had access to a spectrum analyzer like he has. I expect that it would really uncover some issues that I just can't detect without the right test equipment. But that puppy runs over a couple of grand - that's serious $$$! I doubt that I can even rent one somewhere for a reasonable rate. Anybody have any ideas about this?

Get your antenna out of the attic and higher in the air.

This isn't magic, it's physics. He has better toys in his toolbox and the experience to know what is most likely to work. The "average Joe" has neither.

FWIW, a basic SA starts at around $700 on ebay for a Chinese import. You can usually find a handheld SA such as a Sencore 1454 or 1456 for $300-$600 if you're patient and persistent.

Maybe he can't just like I can't put an antenna on the roof for my aunt. Some places won't allow that.

If I thought a C4 clearstream would work I would of tried it. The C2 did NO better then the Terk 55. Inside. Strange as it may seem.

If there's someone closer who might like me to visit with it, though, I can discuss with my parents and see.

11-10-09, 04:45 PM
Well, it does more than I use it for.

The key features are that it'll show what the signals look like just like an ordinary spectrum analyzer. But on top of that, assuming it can decode the signal, it'll provide a SNR (signal-noise ratio) reading and BER (bit-error rate) reading. It's an extremely useful tool and I just love it. If I didn't have school work to do, I probably would not have put it down at all since I got it.

Like Lexus said, it's not always that easy. In my case, I'm in a historic preservation district, and SOMEBODY might get their panties all wadded up about this. As per the HPD's rules, I can't have a roof antenna or a dish. However, there are people who have them anyway, and apparently get away with it. I'm trying to avoid the the dispute. Besides, attic antennas are easier to install/maintain.

He has better toys in his toolbox and the experience to know what is most likely to work. The "average Joe" has neither.

A scientifically-minded average Joe starts off "above average," and toys like these can be purchased, rented or borrowed. Once such toys are in-hand, "Joe" can gain some experience with them, and the next thing you know, he's getting the job done, just like the big kids do with their big toys.

These solutions are not so far out of reach as your initial comments seemed to suggest. With that said, I appreciate that you posted an update.

FWIW, a basic SA starts at around $700 on ebay for a Chinese import. You can usually find a handheld SA such as a Sencore 1454 or 1456 for $300-$600 if you're patient and persistent.

Hmmm... $300 to $600 for a new toy, or $20 to $60 per month, times "forever," to the evil cable/satellite companies? I can always resell the new toy after it has done its job.

Then again, I might just try the roof mount first!

Hey Nervous, I think you're exaggerating! If you get WRNN-48, surely you get WTBY-27 as well! What would we Poughkeepsians do without our 5 SD Gospel channels (WTBY), 1 SD infomercial channel (WRNN), and 1 SD Chinese Propaganda (WRNN-48.2) channel!

With a little work you should be able to pull in W42AE for some Analog PBS goodness, too!

My point is that antenna location is a lot like real estate's three most important things...

Just because you either desire to put antenna in an attic because its easier or do not have the alternative of mounting one externally, doesn't mean that an antenna will work in the attic. If the signal isn't physically present in adequate strength and quality in the attic, you simply cannot receive it in that location regardless of the antenna you try. That's the bottom line.

Location, location, location.

Hey, Trip needs a field project for his new playtoy....

ProjectSHO89
11-10-09, 10:13 PM
What can it do for you ? Just curious:D

Think of it as an oscilloscope for the RF spectrum.

At basic levels, it allows the operator to 1) Measure signal power and signal-to-noise ratios - both critical parameters for digital reception and 2) SEE a graphical representation of the signal - ideal for analyzing multi-path related reception problems.

Beyond that, it depends on the individual device's specific features.

For example, consider the following photo of my 1454:

http://i97.photobucket.com/albums/l223/projectsho89/Antenna%20Stuff/Ch_24_26_Sencore.jpg

These are UHF channels 24 and 26 in St louis at a location where there is no LOS to the towers. The signals are reflected off a nearby hill and some trees.

The signal on the right, channel 26, is of excellent quality with a relatively smooth top of the waveform. In contrast, the waveform on the left, channel 24, is ridden with multi-path and would likely be broken reception-wise for tuners that don't have good capabilities of dealing with such a distorted signal. My little Artec T18AR, BTW, handles it pretty well.

When installing an antenna and using an SA, you'd adjust the antenna so that all the desired channels feature the best combination of signal strength (amplitude) and quality (flatness) making whatever compromises might be necessary to give the best overall signals.

Hey Nervous, I think you're exaggerating! If you get WRNN-48, surely you get WTBY-27 as well!

Sure I can get WTBY. I can pick that one up using a paperclip as an antenna. I was replying to Trip's inquiry about WRNN-LD 26. What I meant was I can only get 48 (WRNN) and not 26 (WRNN-LD). After looking at the coverage map or WRNN-LD, I realize I am too far upstate to pick it up anyway (and WTBY is adjacent on 27).

The best tools for a specific job are rarely inexpensive. Your independent mechanic probably spent at least $2500 for that SnapOn scan tool so he can work on your car's computerized control systems. You can buy a scanner unit for $200, but the SnapOn, in the hands of a trained person, will run circles around the $200 unit from the auto parts store.

I lucked out and got my well-used Secore off Craigslist for a bit over $200. It was $1500 list price brand new. Even after buying a power supply and new faceplate lens from Sencore and making a new rechargeable battery pack, I still have less than $300 invested.

True, but the independent mechanic bought that tool for his business. I doubt any shadetree mechanic would buy that for use at home. Pete Putman probably bought his spectrum analyzer for his business, ROAM Consulting LLC. There's probably not much demand for a scaled back cheaper device aimed at non-commercial consumers. That's why eBay exists. ;-)

In the apartment, with no reflector - hard to say.
What's nice is it's almost too freakin easy to bend up some wire and try a Grey-Hoverman w/o a reflector. 10' of wire, 6 screws & flat washers, a balun and a board. Don't worry about the feedgap of 3.5" this isn't critical. Anywhere close will do, so you could use a 1"x4" to mount to, ending up with around 3" will be fine.

Like David-the-dtv-ma says, putting an eye-hook in the end of the board & hanging it in the window would be giving it your best shot short of getting it on the roof. (You still may need the Terk for it's VHF, and join the two with a UVSJ.)

What I was originally saying is to bribe the super with a 6-pack (12-pack?:D) and sneak one of these on the roof, where it can receive UHF from both directions.

If the 21 digital transmitter is still using the broadcast antenna they used for analog she should receive something from 21 now that it is digital.

The elements are shaped different.

Before I would drive to try any thing I would first try it at your home. I would check around & see what you can find local so it will be easy to return. Some walmarts have a phillips out door yagi antenna. But it is not listed on the web site. It is over priced at $99.00 but that is the kind I would try. If any deep fringe out door antennas you find local I would try them @ your home & see how well they work. Some state the db gain they have & that is like horse power to an engine. If it is not stated it must not be much good or too weak.

The Antennacraft are 4 & 8 Bay bowtie designs, and again will not perform as well as an mclapp perfected design.

What you must realize is many (most) antenna designs currently available commercially were for the entire UHF band - all the way to ch 83. Some were tweaked to improve performance by limiting the high end to ch 69, but even still we are now working only to ch 51 - so with a narrower bandwidth to cover the designs can be optimized to get more gain where it counts.

You can even skip the wire bending part if you use coat hangers as illustrated in this video.

http://blog.makezine.com/archive/2009/01/maker_workshop_dtv_antenna_steadyca.html

This apparently uses a different design than the one discussed in this thread, but the parts are easy to find around the house.

Firstly, he refers to the example in the video as a Hoverman antenna, which it is not - it is a 4-Bay Bowtie. (Actually he may have said Hooverman.:D)
Secondly...
* the Bay spacing of 5-3/4" is too close & s/b 9" apart.
* The element length of 8" is too short - these s/b 9-1/2" Lg.
* The phase line spacing (The wires that run vertically and connect the elements) looks very wide - this s/b 1-1/4".
* The point at which the phase lines cross over each other should have a space of ~1" to approach the 1-1/4" phase line spacing throughout - a piece of electrical tape is not sufficient.
* And the 3" opening at the tips s/b ~5-1/2", though this is not too critical.

Earlier in the thread I posted links to vid's of a properly dimensioned 4-bay bowtie antenna.

It was a very nicely made video, however inaccurate it may be for optimum performance.:D

Seriously, to try a Grey-Hoverman w/o reflector has got to be the easiest and cheapest antenna you could ever try and make!

Here's your bill of materials:
(2) 5' long pieces of #8 or #10 solid copper wire
(1) 1"x4"x3' board
(6) #8 or #10 wood screws & flat washers
(1) balun - 300 to 75 ohm matching transformer (~$5)

Straighten your wires as per this vid:
http://www.youtube.com/watch?v=-8HoeP9beYE

Trim to the overall length calculated from the dim's for the elements on the SBGH-6 (Stands for Single Bay Grey-Hoverman, the 6 is for how many reflector rods is in the design) page of my site, and bend to said dim's.
Attach to board with wood screws & washers with 3" between the elements closest points, putting the balun in the middle - done.

The elements are shaped different.

Before I would drive to try any thing I would first try it at your home. I would check around & see what you can find local so it will be easy to return. Some walmarts have a phillips out door yagi antenna. But it is not listed on the web site. It is over priced at $99.00 but that is the kind I would try. If any deep fringe out door antennas you find local I would try them @ your home & see how well they work. Some state the db gain they have & that is like horse power to an engine. If it is not stated it must not be much good or too weak.

Here's one for you experts to help answer.

As of the past 2 months or so 7.1 which is a middle of the pack VHF station as become my stongest channel. The signal measures in the mid to low 90s. Seeing this is a rather long term event and not due to something that happened one day or one week I can't see this is tropospheric.

Meanwhile 2.1 and 4.1 are in the 60's and 70's and I am having big problems with 2.1

Since I am using what is considered a UHF antenna (CM4228) I can't for the life of me figure out why a VHF channel 7.1 is now my best and UHF channels are a problem.

Is any else having this experience?

Could my antenna have moved a little?

As for VHF channels 7 and 13 are the strongest although channel 7 has been having more mulitpath issues lately. Keeps breaking up sometimes. Still not as bad as channel 47. When they moved from West Orange to the ESB my signal went from a solid strong 90's to 60's that keep breaking up to the single digits. That channel has bad multipath issues.

Hi,
Does anyone know if they are doing work up on the ESB.
My NY channels have been on and off for the last 2 days.
I believe that 7,11, and 13 share the same combiner and they have really been on and off, but so has 5 and 9.
They have been pretty solid since the shutoff, with the exception of 2, of course and I know that 25 is still having problems with their transmitter.
I hope they havent reoriented again.
Any info would be a huge help.
Thanks much

5 and 9 have been doing work - but have not lost signal from them.

The only difference I've noticed with the VHF Combiner stations is that 11's signal
seems worse.

Most stations broadcasting from the ESB, usually do their work between 1 - 5 a.m.

Yesterday 5 and 9 were in and out in the morning until maybe around 9:00 am
Today, 7,11,13 as well as 5 and 9 have been in and out.
I come in around 7, so I dont know what was going on during the night.
I have a 150' tower with individual cut yagi's and all antennas showed crazy variations with signal on my analyzer.
After the leaves came down, my multipath issues were greatly reduced and my NY siganls have been rock solid, so I am hoping that what I,m seeing is just them working in NY and not reorientation of their antennas.

I hope not. Historically, we have had co channel problems with NY during the summer, but usually this time of year, it isnt a problem. I have had some problems when our valley is shrouded in fog, but the high VHF hasnt been effected by this to any serious degree.
My base elevation is 650' plus another 150' tower, so NY has been pretty consistant, 60 miles out. In reality, I am probably asking too much in trying to pull out of market stations in consistantly, but I dont think I can convince 4000 seniors of that. It used to be soooooooo easy. LOL

Wait ... DTV transmitters use vacuum tubes like a 1960s console TV?

Yes, most high power radio transmission uses tubes. Both for FM and TV. In TV , usually higher powered UHF transmitters have IOT's, as Trip said, but some do use Solid State (transistor). Tube transmitters are a lot more energy efficient and produce a better signal for digital than solid state rigs do. Most higher powered UHF TV transmitters have two or more tube transmitters, "combined" together to achieve the power level as well as provide some redundancy. This was more common in Analog where a much higher power is needed.

Could your varying reception be due to atmospherics????

Depends on whether you define atmospherics as sky noise or multipath. Generally, at these frequencies, some of the RF from the transmitting antenna is fired above the horizontal and is bent downward by the refractive index of the atmosphere. This RF arrives at the Rx delayed by this longer path and is dynamic multipath

Actually I have 2 antennas mounted. Both with CM7777 preamps. I have the CM4228 mounted high up on my chimmney and about 10' below it a simple UHF bowtie antenna I found lying around. The simple bowtie feeds my PALDVR as it picks up 2.1, 4.1 better than the CM4228. The CM4228 has trouble with 2.1 (0 reception now) and 4.1 (picture breaks up) where most of the shows I watch/record are located.

What I find interesting is I split the the signal from the CM4228 and send it 70' to an upstairs SHARP LCD TV and that TV will pick up 2.1 although the signal is not that strong. I only send it about 10' from the preamp in the basement to the first floor TV and I can't get 2.1. I have tried all kinds of variations on splitting and not splitting the CM4228 signal, inputting to the TV or the DVRPAL and the results are the same. The first floor devices closest to the preamp can't get 2.1 at all or very well and the second floor TV can get it.

By the way this is a recent event as all summer 2.1 was coming in in the high 80s to low 90s reception wise and was along with 5.1 my strongest channel. Then all of a sudden 5.1 and 7.1 became my best channels and 2.1 bad.

However as I said the small bowtie has picked up 2.1 fine.

There is something strange going on....maybe with the coax, ground, or connectors. I have switched things around again and again, replaced coax inside etc.

Hi Len, how's it goin!:)
A couple of things to consider would be the change in those channel's output since summer - tvfool at my location out on L.I. says signal strength has dropped considerably since early/mid summer, I think (hope!) due to work on the ESB transmitters/antennas.

Another possibility is that we're talking UHF here and it will be considerably attenuated by the leaves on the trees. Add to that as I recall you also trimmed some trees at the end of summer letting even more signal thru - and now all the leaves are gone.

It may be that since the 7777 is a high gain amp, and your problem is with the TV closest to the amp, that you may be overloading the tuner. Just for giggles try putting a 2, or 3-way splitter in front of that 10' of cable to the 1st floor TV to drop the signal to be close to that which the upstairs TV sees, with a 70' cable run, and see if that makes a difference.

However as I said the small bowtie has picked up 2.1 fine.

There is something strange going on....

Since your location is on the downside of a hill you are probable looking at both refracted and reflected signals and the 4228 may be a little too high to be in a strong signal area, where the old corner reflector bowtie being a bit lower is in a strong spot - it doesn't take much difference in height to make all the difference between being in a hot spot or being in a null...

Or the corner reflector bowtie is a bit more directional than your 4228 and thus a bit more resistant to multipath at your location.

Or... the gain of the bowtie is lower than the 4228 and thus when amplified is still not overloading the tuner closest to it.

Some thoughts...

Maybe it has to do with the bowtie antenna being lower to catch signals that may be bending over the hill near your house. I noticed that in this article the antennas are placed low to the ground and angled slightly upward towards the hill take advantage of knife edge refraction. Here's the original article:

Thanks Guys for the tips/ideas!

AKA....you sure have a great memory for my situation! You nailed it.

I have already tried sending the CM4228 right out of the preamp to the TV 10' away with no split, then tried sending a coax feed from a 2-way splitter and a 3-way splitter. 2.1 still did not come in at all. Zero.

Meanwhile like I said a TV on the second floor getting the feed from the basement to the attic and then across the attic floor and down a wall into another SHARP LCD can receive 2.1 with a signal in the 50's and hold it for the most part with some breakup.

This issue really has me puzzled. Makes no sense to me. Must be something stupid I am overlooking. I keep thinking about it and open to suggestions.

The CM4228 is a bit high up on the chimmeny and I dare say I don't think there is a rats chance in hell that I will climb that high up and try to move it lower or higher. It's not that it is so high for most people....but I am chicken.

Do you folks think there is any relation to the fact that I can receive 7.1 so strong (upper 80's and even low to mid 90s) and 2.1 seems to disappear?

Why is a VHF channel my best when I have what is considered a UHF antenna? In fact I can get 11.1, 13.1, 58.1 (8)....all VHF stations and I can't get 2.1. This seems very odd to me.

Do you folks think there is any relation to the fact that I can receive 7.1 so strong (upper 80's and even low to mid 90s) and 2.1 seems to disappear?

Why is a VHF channel my best when I have what is considered a UHF antenna? In fact I can get 11.1, 13.1, 58.1 (8)....all VHF stations and I can't get 2.1. This seems very odd to me.

I think its not always about the signal strength, it may be more about signal radiation pattern and purity of signal (how strongs are the reflected signals causing impurities). During summer months 2.1, 4.1, 5.1 were consistetly strong for me. After the digital transition, I was not getting 11.1 at all and 7.1 and 13.1 were mutually exclusive, i.e. if one was coming, I was missing the other. Now as time progressed ABC improved considerably even though they are in VHF and now I get it reliably. Probably they did some thing on their side. After the leaves were gone, now I am getting 13.1 relliably during evening and night and 90% reliably during the day. 11.1 also improved a lot (I was not getting it at all before) and now I get it reliably during evening and night. And as you have noted and I have observed too, 4.1 now breaks up some time. Same with 2.1 too but less. FOX and ABC are the strongest for me. I wish all the stations move back to UHF and use pre-transition radiation schemes, but figured, that'll not happen at all.

Your experience with the NY channels is very much like mine. I don't know where you live but I feel better reading your post.

I still can't figure out though why a TV 10' from the preamp can't lock in channel 2.1 and another one getting a split signal more than 70' away can lock in at 55% with some breakup.

I will continue to work on it....though I am running out of options.

I'm on the south shore of Long Island at 58 1/2 miles out & pretty challenged - the north shore generally seems a bit better. If you're on the Island at >60 you may have an even worse shot. If however you're in Connecticut, the LI sound will be your friend and you should be in much better shape.:)

AKA....you sure have a great memory for my situation! You nailed it.

Yeah, like a steel trap baby!:D LOL

I have already tried sending the CM4228 right out of the preamp to the TV 10' away with no split, then tried sending a coax feed from a 2-way splitter and a 3-way splitter. 2.1 still did not come in at all. Zero.

That would apparently eliminate overloading the tuner as a possibility...

Meanwhile like I said a TV on the second floor getting the feed from the basement to the attic and then across the attic floor and down a wall into another SHARP LCD can receive 2.1 with a signal in the 50's and hold it for the most part with some breakup.

This issue really has me puzzled. Makes no sense to me. Must be something stupid I am overlooking. I keep thinking about it and open to suggestions.

...I still can't figure out though why a TV 10' from the preamp can't lock in channel 2.1 and another one getting a split signal more than 70' away can lock in at 55% with some breakup.

I will continue to work on it....though I am running out of options.

I assume you've tried different cables to the downstairs TV, thus eliminating any chance of a connector/cable problem?
Then next is to compare tuners at the same [close, 10'] location. You mention a Sharp TV, but I thought you said you were using the DTV Pal DVR at that location? If so, that may explain it as from what I've heard that has a far better tuner than the average TV...

Lexus, I like to add to CC, small TV like my 13Sharp have only one CC-1, more complicated and larger TV like Sony20+have CC1.2.3.4.+ Text1.2.3.4, the CC are only forTV,
The CC for Conv.box use only Service1-6.
INet/Tivax type have small letter Service CC, no good, another box Coship has excellent size sligthly larger than CC on SonyTV, but it has advantage that you Customize to transparent-translucent yellow or darker Large size Font4 or 7, so you can see through
the CC what's going on TV, as You know TV CC blocks the space, Enjoy, Alo.
The Service 1cc is in broadcast language, the S2cc is added tongue, S1ccEspanol/ S2ccEnglish and vice versa, I know the English majors have S2ccEspanol.
One more trick, if you have small screen tv13"+, first customize, use only Solid letters, then go Automatic, you get good small CC.

From the preamp I split the signal to feed the first floor TV and then the feed from the basement going to the second floor is through another splitter that is feeding the Sharp LCD in one room (that is the longer run from the basement of about 75') and an analog TV in another room (that is about 30' from the basement) with the signal coming to the TV via a converter box. As an aside I have 3 converter boxes that I have been using at various times and now I am using the PAL. Both TVs on the second floor receive 2.1. I tried going right from the preamp to the first floor TV and still no 2.1.

Yes I have tried all kinds of cable swapping with that first flloor TV but I will try some more to rule out that possibility. I think I ruled it out though.

OK, lets go thru the numbers for each TV for ch 2.1 (RF33) from the amp, but not including the cable from the amp to the 1st 2-way splitter as it's a constant.
You didn't say how much cable is between the 1st & 2nd splitters, so I estimated it at 10'

Downstairs TV:
1st 2-way splitter = 3.5dB
10' RG-6 cable = 0.53dB
Loss to tuner = 4.03dB

Digital box TV upstairs:
1st 2-way splitter = 3.5dB
10'(?) RG-6 to bsmt = 0.53dB
2nd 2-way splitter = 3.5dB
30' RG-6 cable = 1.59dB
Loss to tuner = 9.1dB

Sharp TV upstairs:
1st 2-way splitter = 3.5dB
10'(?) RG-6 to bsmt = 0.53dB
2nd 2-way splitter = 3.5dB
75' RG-6 cable = 3.98dB
Loss to tuner = 11.51dB

You're using a high gain amp in the 7777, intended to overcome a whole lot more than 4dB of loss.;)
You have a difference of over 5dB between the downstairs TV & the closer of the 2 upstairs that both work - the stronger of which is seeing only 31% of the power that the downstairs TV is.

Here's what I would try first: Add a 3-way splitter in addition to the 2-way you already have to the downstairs TV. Hook the feed up to one of the 7dB legs (not the 3.5) so you're adding in another 7dB of loss to that TV - thus putting the signal strength close to the signal level the Sharp is seeing.

Terminate the remaining ports to eliminate any possibility of creating multipath on the line from reflected signals on an open splitter. (If you don't have terminations just hook cables to your extra converter boxes.)

Yes I have tried all kinds of cable swapping with that first flloor TV but I will try some more to rule out that possibility. I think I ruled it out though.

If you tried a different cable for the 10' run, and different legs of the splitter I doubt it's a cable/conn problem. (You did flip that 1st splitter didn't you?:D)

Both 2-way splitters are in the basement close to the preamp and only about 2' separate them.

As to your suggestion about adding another splitter to cut down on possible signal overload to the first floor TV ...I will try that today and get back to you. The downside that I see is that while I may now get 2.1 if that is truly the issue, I may lose signal on other channels. It will be interesting to see what happens! Terminating all of those outputs will be a challenge though.

Thanks!

Have you ever tried swapping the first floor TV with one or both of the second floor TVs or tuners? I'm thinking that there's either a difference in tuner sensitivity/selectivity/etc or there's some localized EMF noise near that first floor TV that such a swap might give you some clues about.

akahooper

Both 2-way splitters are in the basement close to the preamp and only about 2' separate them.

The actual amp is on the mast at the antenna, the splitters in the bsmt are near (And hopefully after) the power injector. I just wanted to clarify you have the amp in the right place where it's doing the most good.

So we have a min difference of 4.67dB not 5.07 - a bit less but you still never know.

Terminating all of those outputs will be a challenge though.

What you're doing is disconnecting the 10' cable from the 1st splitter, and adding either a short length of cable or a M/M feedthru to connect the 1st splitter's output to the input of the 3-way. Then connect the 10' cable to a 7dB output of the 3-way and terminate the remaining 2 ports. Lowe's by me sells a 4-pk of term's for ~$5.00 I think - or just connect your spare converter boxes w/cables as I mentioned.

Have you ever tried swapping the first floor TV with one or both of the second floor TVs or tuners? I'm thinking that there's either a difference in tuner sensitivity/selectivity/etc or there's some localized EMF noise near that first floor TV that such a swap might give you some clues about.

This may very well be the case. But since as you say, different tuners have different sensitivities and resistance to overload & interference it becomes difficult to nail down. IIRC his downstairs TV is a 46", which isn't the easiest to lug around the house - especially if it's wall mounted.;) While it would be easy enough to try one of his converter boxes that has been successful upstairs in front of his downstairs TV, this doesn't solve the problem, (as it would nix HD) and in the end what does it tell us? As mentioned above, every tuner is different...

Thanks for the idea! Actually I had at first rejected the idea of bringing the TV from upstairs down to the first floor as I was thinking only in terms of the SHARP LCD (32") which I'd hate to do because of size and weight but then I thought why not bring down the analog TV with the PAL converter box as that is more manageable and the results will be very telling too.

So your suggestion is a good one and I will try that too and let you know.

LenL
11-23-09, 03:03 PM
I think I will try Rothes suggestion first. It will be easy to simply disconnect the coax from the first floor LCD TV and run it into the PAL converter box and then into the analog TV I will bring down from the second floor.

If that TV picks up 2.1 then that will be one key fact to work with. If that TV does not pick up 2.1 and now behaves like the first floor TV then we know it is a problem with the feed, overload or whatever and not the Sharp LCD TV tuner. I already know it is not the Sharp anyway as if I feed it into the tuner of the DTVPAL DVR and bring the HDMI feed into the Sharp TV I still don't get 2.1.

After I get these results I will work in the basement on adding some more split to the signal and terminating connections with the other converter boxes I will bring to the basement.

For some reason (ignorance) I assumed the box with the power chord that is in the basement is the actual amp and what is at the antenna outside is just some other dumb device. Anyway I have the CM7777 configured correctly. The part that goes with the antenna is with the antenna and the part that belongs inside is inside.

LenL
11-23-09, 04:13 PM
I brought the analog TV to the 1st fl with the Pal converter box and was able to receive 2.1 in the low 70s and locked on good with no loss. Better than upstairs. I checked the other channels too.

So I unhooked and brought the cable into the PALDVR to LCD TV via HDMI and the reading for 2.1 were about the same as were the other channels PAL converter box compared to PALDVR.

So it looks like the issue is the tuner in the SHARP LCD TV on the first fl. not picking up 2.1. I guess it is fussier.

So I am happy that the PALDVR can get the channels, expecially 2.1 and 4.1 and they are good....so far.

Not sure about doing anything with splitting the coax etc experiment at this point. I will keep that in my back pocket.

Thanks guys!

AKA....yes I was combining both antennas at one point and that was going well until I lost 2.1 all of a sudden so I ditched that idea.

Also I'll post you over on Yahoo about the home built. Some new developments to tell ya about.

Interesting findings, LenL. While I recognize AKAHooper's point that there are more variables at play here than what would allow for an easy determination of the cause of your reception problems, you have nonetheless given yourself some more information to work with.

It does seem that there's something about your Sharp's reception - or maybe the environment in which it's mounted. I've seen power transformers - in my case, the one in my home theater PC's battery backup system - cause some minor reception problems. That was an issue that I didn't pick up on until I bought a gauss meter. (I also found two ghosts and a possessed refrigerator in the house, but that's another story.) Anyway, is there any chance that the Sharp has an external power transformer that happened to be mounted/sitting right by the TV's tuner circuitry?

I know, I'm reachin' here....

WNYE (25.1) has returned OTA, albeit with a weak signal.

Those tubes are very expensive. Most high power stations have 2 in a push pull power amp.

If one goes out they will run at 40% power off the other good tube.

but if one tube shorts out it will stop all the power out of the amp. If that is the case they may just remove the shorted tube & run on the other good tube. It may be at 35% power because of the miss match with out the other tube.

Also the workiing tube may be weak.
But they may run on it until it fails.

they may run like that while funds are low because of the weak economy .

Actually I do have the PALDVR sitting right in front of the SHARP TV which might be a problem. I'll have to move it and see if that changes anything.

The more I was watching 2.1 fed from the PALDVR the more I was able to see that there was still an issue with my reception of 2.1. At least I can get it on the 1st fl but there is still a reception issue.

I took the feed from the 2-way splitter and passed it to a 3-way splitter. Two of the outputs went to converter boxes to terminate them (not plugged into outlets) and the remaining output went to the 1st floor TV. No improvement to channel 2.1 and some signal loss on other channels. I even added another 2-way splitter between the 3-way and the 1st fl TV and no improvement.

I've had a few private messages with Trip regarding the Spectrum Analyzers that we each just purchased, and thought I might share some findings with the rest of the group. I just used this thing for the first time this weekend, and it was very revealing about my own particular installation. Whereas my home theater PC's tuners and software would, at best, tell me that I have a strong signal level (or none at all) coming out of my preamp, I had very little information available about the quality of that signal. The spectrum analyzer changes all of that. See the pictures and comments at:

11-30-09, 05:49 PM
Nice pics, Jim. However, if you had a null modem serial cable, you could use the SMART software to get the readouts on your computer instead of trying to take pictures of the analyzer. Unless the antenna was too far from the computer, in which case, this is fine. :D

Any chance you could get a picture of channel 55? I'm curious to see what that looks like. And are you sure that the noise above channel 22 was actually noise and not signal from WNJS-22 as noted on your TV Fool plot?

The WMBC-18 and WNYW-44 pics are textbook multipath. Actually, they look pretty good compared to my indoor antenna setup here, where I see usually one huge gouge in the middle of the signal rather than a gentle ripple like you have.

I would also be curious to see what 31 looks like, as that's one you skipped over. What you have listed as WPXN-30 is actually WFUT-30.

Are you enjoying the analyzer? :D

*IF.* 'Nuff said. Besides, that big button on the top of my point-n-shoot camera is much easier to work with than baud rates and parity bits and stuff.

Any chance you could get a picture of channel 55? I'm curious to see what that looks like.

When (if?) I get home tonight, I'll take a look at it. FWIW, it's not in my usual channel line-up, which probably means that I didn't get enough of a signal to justify trying to tune it in.

And are you sure that the noise above channel 22 was actually noise and not signal from WNJS-22 as noted on your TV Fool plot?

Maybe. But my antenna is aimed at about 15 degrees E of magnetic north, which would make for a might weak signal from any station to my west. FWIW, that station would be in a dead zone for my antenna, and looking through roofing shingles, too.

I'll fix it later, IF I get home tonight. And I'll take some shots of 31, too.

It's great to actually be able to SEE what my tuners are seeing. There's probably so much more that this thing could tell me. Experience comes slowly, but that's part of why I posted these pics - to gain others' experiences.

I found the default settings to be sufficient for making it work. I suspect not having the cable to be the biggest problem; I know it took me a while to find one. :)

It shouldn't be in your lineup. Channel 55 is Qualcomm's MediaFLO service. It won't decode on any receivers besides their own. I'm just curious if you're able to see anything from it and if so what it looks like. (I have no service from them in my areas.)

Maybe. But my antenna is aimed at about 15 degrees E of magnetic north, which would make for a might weak signal from any station to my west. FWIW, that station would be in a dead zone for my antenna, and looking through roofing shingles, too.

Then it sounds less likely. I was just thinking out loud. :)

Where is this textbook that would tell me what such spectrum charts look like?

I don't know that there is such a textbook, I just know that's what I've been told traditional multipath looks like. It's the kind of picture one would expect to see in a textbook, I guess, is how I should have phrased it. :D

I'll fix it later, IF I get home tonight. And I'll take some shots of 31, too.

Alright. You missed WXTV-40 as well, but I don't know how much it matters. I know I don't watch the Spanish-language channels when I'm in the area, and it's not yet in HD anyway!

It's great to actually be able to SEE what my tuners are seeing. There's probably so much more that this thing could tell me. Experience comes slowly, but that's part of why I posted these pics - to gain others' experiences.

Absolutely. I love my analyzer for the same reason; even on the indoor antenna it lets me clean it up enough to where it'll decode cleanly even if the plots look just awful.

If there's any questions I can answer for you either about the output you're seeing on the analyzer or as far as how to use it, let me know. I'll be glad to offer any advice I can give.

Trip and James,

Try this: www.sencore.com/uploads/files/AchieveGoodHDTV.pdf Please note that the document, which is several years old, is EXTREMELY conservative in its described signal range as the newest crop of tuners in CECBs has about an 80 dB dynamic signal range.

FWIW, a simple USB to serial adapter plus a F-F null modem adapter are all you really need to connect to the Sencore via SMART.

Multi-path is made visible on the SPEC screen as the ragged top of the waveform and numerically as the peak-valley number on the MEAS screen. This is very evident in your channel 44 photos. Attached below is an example of a nasty RF24 and a pretty clean RF26 side-by-side. Photos were taken earlier this year before I got into SMART.

I suspect that some of those "shoulder" noise levels are due to IMD in your pre-amp, ie channel 33.

Hey Trip,

Here are the measurements and spectrum graphs that you wanted of channels 31 and 55. Interestingly, both signals seem to be pretty strong and clean. Channel 31 is not nearly as strong for me as the adjacent channels, and interestingly, channel 55 is not flat across it's range, which makes sense considering your description of the signal. I'm actually surprised that the FCC lets them broadcast a scrambled signal in the OTA DTV band.

Anyway, one of these days, I'll re-scan all of the channels that the spectrum analyzer can receive, as opposed to just the ones that I've put into my tuner's channel line-up. I'll post an update here when I get around to that.

I probably have one in a box around here somewhere. You're going to make me dig into those boxes, aren't you?

I've been thinking about those spectrum graphs, and it now makes sense to me that multipath interference would create a frequency response graph like this. Every time you add a reflected signal (light/sound/RF) to a source signal, you're going to create standing waves at certain frequencies related to the difference in distance traveled by each signal's path. Those frequencies are made clearly visible by the spectrum graph. Cool. (I can see! I can see!) :D

Photos were taken earlier this year before I got into SMART.

Clearly, I have not gotten into SMART yet, and my SA1454 and its CD is at home. What will SMART do for me that photographs won't?

I suspect that some of those "shoulder" noise levels are due to IMD in your pre-amp, ie channel 33.

This is the one comment of yours that just isn't coming clear for me. What is it about IMD that would create such a graph?

Remember that the OTA DTV band now stops at channel 51. Channels 52-69 were auctioned off. Qualcomm's MediaFLO is one of the services using that spectrum, and it uses channel 55 nationwide. I have a page for it up on RabbitEars.

I asked about it since Qualcomm actually has a 22 kW transmitter in Monmouth Beach and a 50 kW one in Tinton Falls. I wanted to see if it looked like it had severe multipath in it or not, which it surprisingly doesn't seem to.

to follow up can you scan the signal of channel 51 or 18 from montrclair nj, on your spectrum. i cant get a signal from either one, I have my antenna pointed towards the transmitter towers, my tv fool says it should come in very strong, I'm 18 miles away, i do multipath from buildings in my path but that shouldn't wash out my signally totally, I get esb signals at or near max,

Ummm... well, two things:

1. First of all, I already did. Both 18 and 51 are already on that web page that I set up. See http://www.jimrothe.com/hdtv_ota/attic/index.html.

2. HOWEVER, as SnellKrell has already pointed out, my reception conditions are going to have very little bearing on your reception conditions. We're in different environments, with different terrain and nearby buildings, with different antennas, amplifiers, cables, splitters, etc. The only thing that my spectrum analysis is really going to tell me is what's going on with MY signal - not yours. Even my next-door neighbors would only see minimal relevance from my scans.

What you need is to do a similar spectrum analysis at your location, with your setup. You can buy one of these things on E-bay, like Trip and I did, or you can hire someone who has one and knows how to use it, or - maybe someday - you might be able to rent one from somebody who has one. (I'm thinking about this, but am far from committed to the concept. If someone beats me to it, I won't be terribly upset.)

Anyway, abandon any hope of gleaning any information that's relevant to you from the analyses that I'm doing. As much as you can hope for is to replicate the process of measurement and adjustment that I'm going through, and I haven't finished that process to a successful conclusion yet, so I can't even tell you that this process (and equipment) is cost effective.

Sorry to burst your bubble about this stuff, but you're going to have to get your own data.

12-01-09, 06:06 PM
what i was trying to deduce from your analysis was that possiblility the signal from nj is not reaching western queens as well as other parts the nyc skyline would could cost extreme amount of multipath of the signal to this area, thxs for you insight

Rothe and Trip,

Thanks for sharing all of your data and info in this area. I am finding it very interesting.

I'm here thinking ...ok I go out and get me one of these expensive gagets and get these readings as my buddy Rothe has done down in Monmouth County and then what?

It is going to tell me exactly what I am seeing when I watch TV? That some channels suck and others are great. I suppose I could if I was not afraid of heights go climb the roof and adjust the antenna and take more readings. But then I would see and get the same results by simply viewing the reception.

So guys....why would anyone but an antenna installer want to spend money on a spectrum analyzer? I guess I'm just too practical to spend the money unless they are cheap, cheap, cheap.

Folks,

Any thoughts on what this might mean for NBC 4.1 OTA? Can Comcast pull the plug or reduce OTA support in the NY Area? I don't see how they would want to continue OTA. It would be better for them financially to pull the plug to encourage people to get their cable service.

It has nothing to do with a new owner and what he "wants."

It has everything to do with Congress and the FCC!

There are laws and regulations and until they are amended or changed,
everything will remain the same.

Here's something to gnaw on. There has been speculation that Comcast would sell-off the NBC owned station and the TV network. The philosophy
being - less regulation and speed bumps concerning the deal, yesterday's media and money losers!

It will probably tell you WHY some channels suck and others are great - weak signal, noise, FM interference, multipath, etc - and you will be able to see these things on the display. Can you make that determination by just looking at the TV screen?

Once you have more information, it might help you to determine if there's something that you can do to improve the situation, or if it's all just a lost cause. As I said yesterday, I haven't finished yet, but I do have more information to go on. As they say, "stay tuned...."

So guys....why would anyone but an antenna installer want to spend money on a spectrum analyzer? I guess I'm just too practical to spend the money unless they are cheap, cheap, cheap.

Here's another way to think about it: you spend $400 on a used spectrum analyzer that helps you to maybe/finally optimize your OTA reception system, thereby allowing you to continue saving $20 to $70 per month by not having a cable or satellite TV service bill. When you're done with the spectrum analyzer, you put it on back E-bay and get $300 to $400 for it, in which case you're out a whopping $100 max, and you got your problem solved.

Or you keep your new toy because it's cool and it's fun to play around with.

I kinda suspected that you looked at this as a 'toy' and that's OK. I suppose I am a bit jealous as I could have fun with it too but like I said...I'm cheap, cheap and more cheap.

So I will stick with just using my eyes looking at the TV and the signal strength being shown by my TV or PAL DVR as a guide to what's going on.

I know my antenna is pointed at close to 119 degrees which is the compass direction the ESB is from my house. I can't do much more than that. Trees are out of the way and I don't think I can dig and remove the top of the hill I am facing. Sometimes you just have to accept the situation and toys are not going to help.

One of the earlier comments on the spectrum analysis charts that I posted came from ProjectSHO89:

I suspect that some of those "shoulder" noise levels are due to IMD in your pre-amp, ie channel 33.

I was kind of hoping he would chime in on my request to elaborate on that comment, but he hasn't. Now, I'm wondering about a nearby FM radio station - it's transmitting about 100 watts, but it's just a few blocks away - that has previously wreaked havoc upon my reception of an adjacent FM channel. (The offender is WYGG; the desirable adjacent station is WBGO. If you want to look at FM Fool (www.fmfool.com), I'm in the eastern section of the 07756 area code.

The Channel Master 7777 preamp that I'm using has an FM trap, which is enabled, but I could only guess that I had it tuned right - all that I had to go on was the signal strength digital bar graph on an audiophile grade separate FM tuner, and that graph wasn't granular enough for me to really be sure that I had the best settings on the FM trap. Now that I have the spectrum analyzer, which covers the FM band as well, I'm going to revisit that adjustment this weekend.

But here's a question to ponder in the meantime: could an FM broadcast overload a preamp in such a manner as to cause this intermodulation distortion which ProjectSHO89 spoke of?

In case nobody said it yet, the nonHD OTA crowd may want to know that there is 1 movie channel showcasing every day in prime time - the ION31-3.
Though it is the oldies like Magnum force, the Rookie, Heat,Nat. Lampoon etc. but it is good to know that at long last some of the multiplex stations use it for something useful, wonder when, when wabc7-2 will follow.
Also the KoreanMBC 17-2 shows lots of good shows all with English

How come when rain comes the signals coming to TV via conv.box are apparently more steady and stronger? It seems to me that rain adds energy to it or limits bouncing, keeping multipath more narrow as it should be.
On the other hand similar things could be said for good sunny days, right?
