Looking that the list of stations and the resolution for them, I saw that Channel 7 in Washington DC is listed as 480i.

Is that how it has always been?

Do they broadcast in 480i always?

7.1 is 720p, but doesn't look nearly as good as WMAR. WJLA's equipment is FAR from state of the art. OTOH, the same programming looks great on Newschannel 8.

But seriously there is NO WAY you would get channel 68 this far out w/o some extreme tropo activity. I'm sure AntAltMike has never decoded 68 from the MANY high rise buildings he has been on.
AntAltMike gave me permission to post through his member account after he was admitted to a local hospital this morning for treatment of self-inflicted damage he did to his tongue after reading post #14,159, but I am concerned that if he ever visits the mgrunes(dot)com/comcast linked page upon his release that we will lose him again when he is forcibly admitted to Bellevue.

It is fortunate that those results were posted before the sun came up, as otherwise, Mike might have broken his neck trying to replace his Winegard PR-9032 and his CM-4228 in the dark.

Ummmm... ahem...

So everyone understands...

That long list of channels comes from TiVo's database.

It is most definitely NOT, repeat NOT, a list of channels being received by the antenna.

So I wouldn't rush to the patent office just yet...

Not so.

I listed reliability (A, B, C, D), as I received them. Some of the D's I haven't received, but most of them I have received once. A is always there, B usually is. C is somewhere around 50%, so I ignore C and D channels, and only use B when I must. Channel 68 is D, and I've never received it.

Also, I corrected what TIVO said, regarding channel names. I should, however, correct a few more channel listings, but haven't got around to it.

As far as patents - I think bare wire is a pretty old idea, that dates back to Marconi, maybe even to Tesla. A ham radio operator tells me that it is very common to string a wire up to a tree branch, and back down, in an inverted V pattern. It's not very directional, and isn't precisely tuned to your frequency, but is otherwise very effective. Sometimes they get fancy and create a true center-tap dipole, and they usually match impedance and ground part of it, but I'm lazy.

Also, someone I know who worked in the comm station on an aircraft Carrier during the Vietnam war tried replacing the Navy's fancy antenna with bare wire, and it worked better there too, though of course they went back to the Naval spec'd antenna. So the idea is at least that old.

My personal conclusion is that a lot of antenna ads are pure hype - especially the unidirectional indoor antenna ads. One doesn't really need a $40 - $60 amplified antenna that one casually mounts behind the TV.

OTOH, not everyone has an attic. And the biggest factor in signal strength seemed to be how high I mounted the antenna. So it's almost certain that a well-designed roof-top antenna must do better than anything in the attic. I wouldn't trust a simple bare wire anywhere it could be hit by lightning.

“Rarely” is not the same as “never”. Some of those channels you will never receive, because they don’t exist as listed. They are errors in TiVo’s database.

And to suggest or imply that that list represents “local reception in College Park, MD” is grossly misleading, plain and simple.

Is anyone else having issues with WRC/NBC (4.1) and WUSACBS (9.1), particularly at night? I've recently made a fair number of changes to my wiring set up, so the issue may be somewhere in my new equipment, but I've noticed over the past several nights that at night both of these stations seem to be coming in much much worse than the others, (though they all seem to drop in quality at night). This is using an Antennacraft HBU-33 antenna in my attic. It's worked reasonably well for a long time, though it's possible some of this stuff has been going on since before the changes to my equipment and I simply didn't notice (haven't really watched many shows on CBS in a long time, and NBC has usually come in reasonably well for watching but has occasionally had problems in the past (I also haven't been watching any shows on NBC regularly in a year or so).

Anyway, I'm still trying to evaluate if it's some of the new wiring or the new distribution amplifier that's causing these problems, but I wanted to check to see if anyone else was having issues.

Here's my TV Fool report in case it's helpful: http://www.tvfool.com/?option=com_wr...8e0310c9f131d3

Why are you using a distribution amplifier? What model? What previous model? What kind of reception do you get if you take the amplifier out?

Thanks for the quick reply.

I'm only just starting to investigate the issue, so I haven't tested everything, but I'm using at distribution amp (8 way) because I'm feeding to 6 outlets (soon to be 7). I'm currently using this one: http://www.amazon.com/gp/product/B00...ilpage_o04_s00, and was previously using something very similar to this one: http://www.radioshack.com/radioshack...r/1500473.html.

I haven't yet tested what happens if I connect the antenna directly to my main source (in this case an HDHomerun Dual), mostly because at the start of all of this I was having some issues with the connector on the end of the coax, and so once I got things more or less working I didn't want to mess with that part too much. Hopefully I'll have some time to do more thorough testing in the next week. So far I'm just trying to eliminate variables as much as I can while I'm at work and not able to spend time with the wiring at home. I figured if others were having the same issue it might offer me some kind of clue.

What seems so odd to me is the way the signal seems to vary so much with the time of day. Everything seems to be worse at night, but those two channels in particular have been giving me trouble.

I'll give some background on what's changed and why:

We recently had a big renovation done to our kitchen and upstairs bathroom. During said renovation I decided to try to make the wiring situation in the house a bit more straightforward and had them run a wire directly from the basement utility room to the attic, and add in some new coaxial jacks in a number of rooms throughout the house, all coming back into the basement utility room.

Previously we had coax cable that dropped out of the attic vent, and then went to a two way splitter which fed into one of the bedrooms upstairs, and then back around the outside of the house down to the ground and finally into the basement, where it was attached to a radioshack 4 way distribution amplifier (similar to this one: http://www.radioshack.com/radioshack...r/1500473.html), though only three of the outputs were in use at theime (the last one was terminated). the run from the attic to the basement was much longer and ran along the outside of the house.

Unfortunately I didn't take as good a note of how things were doing before I started switching things out, though subjectively everything seemed pretty good, but again we weren't watching as many shows on those two channels then, so it's possible they weren't doing well in the last year or two and we simply didn't notice at the time.

Ok, a bit of an update. I just hooked the (new) coax from the antenna directly into my HDHomerun. Signal quality was roughly the same to slightly worse for all channels, so I think I can eliminate the distribution amp as the source of the problem (of the signals getting much worse at night). At some point I'll try to hook everything up through the old coax cable and see what happens, though the last time I did that I found it to be roughly the same as the new coax, but it's also possible I didn't have a solid connection on one end or the other.

Which reminds me that I'm now remembering that the last couple of times I was up in the attic hooking the coax up to the antenna it felt like it was tough to get a good connection to the matching transformer hanging off the antenna, I may see about ordering a new one and seeing if that improves things...

Updated Bare Wire Attic Antenna Channel List, College Park, MD

Since folk didn't like that I listed channels that my TIVO box thought I should get, but didn't, I've updated this. I also removed some channels that I recently only got for a few minutes. And for some reason, channels 66-1 - 66-6 used to be completely reliable, but aren't any more.

I have also updated http://mgrunes.com/comcastNum.html, which includes COMCAST channels too.

Please note channel reliability in the Q column - some of these channels are unreliable.

Since I can't figure out how to format this, I have attached OTA.txt, with columns aligned.

------------------------------------

A summery of my results (detailed at web site listed above) for Local reception in College Park, MD, from an attic antenna, created by stripping the last 7 or 8' of shield from a cheap coax cable. Cable was simply strung on top of the highest cross braces. Total cost: $5 - $10 for the cable. The other end of the cable was plugged into an old TIVO series 3 DVR.

Note that many network affiliates actually create their own programming in early morning, and that PBS affiliates schedule times independently, and include a lot of their own programming.

Many network affiliates create or buy their own programming for use on sub-channels other than 1. Most of these are not carried by the COMCAST cable network.

Abbreviations

Ch# = Channel numbers, in nominal "channel-subchannel" form.
Fr = Analog channel frequency band, from pre-HD days.
Q = Reliability: A=100%, B=90-100%, C=40%-90%, D=<40%.
Resl = Resolution, in vertical lines, p for every frame, i for interleaved frames.
Name = Station name, and/or network affiliation.

What is "signal strength" on a TIVO 3 DVR?

What is "signal strength" on a TIVO 3 DVR?

There is a value my TIVO DVR gives, between 0 and 100, for each channel, if you select the "signal strength meter".

For the best reception channels it is in the 95-98% range. For the worst that I reasonably often receive, it peaks around 25%-30% (varies a lot). The highest signal strength channels tend to be the most reliable, but that isn't a perfect correlation. E.g., on my older antenna, the values were lower - 30% on the most reliable - and they were very reliable, whereas 30% channels on the better (bare wire) antenna are unreliable.

At first I assumed it was proportional to the antenna signal amplitude or power. But that makes no sense. I remember reading (in the old analog days) that any receiver has an amplifier with an Automatic Gain Control that covers a few orders of magnitude of signal strength - that I assume applies on a per-channel basis. I assume this is still true.

(Though an electrical engineer who did analog chip design tells me circuits have changed in the "modern" era - i.e., reception for each channel is no longer done using a tuned circuit, with something like a variable capacitor. Now the input signal is mixed (heterodyned) with a frequency near the carrier, in several stages, to produce intermediate frequency bands, and the upper or lower frequencies selected, to produce the final result. I suppose the AGC might now be set by the strongest channel, over the entire TV spectrum, rather than each channel - but that would seem sub-optimal, since it would make it hard to receive weak channels.)

Is "signal strength" on some sort of logarithmic scale, or is it a noise/signal amplitude or power ratio?

I live in Eastern Loudoun County. At this point, I'm only having issues with Channel Five. I have a RCA Compact Outdoor Yagi HDTV Antenna about 15 feet or so off the ground pointing at DC. I found that if I took some time and carefully worked with the antenna using the strength meter in the TiVo to get the best reception. Channels Nine and Four have not been problematic for me lately.

Interesting, Channel Five is probably the channel that comes in the most clearly and consistently for me. I never have any trouble with it. The past few days and nights things have been generally better reception-wise. With the exception of Monday night, when it was in the lower 60's, occasionally dipping into the upper 50's of signal quality, Channel Nine has mostly come in pretty well, in the 70's to 90's most of the time, occasionally dipping into the upper 60's (on signal quality). Channel Four (WRC/NBC) is still giving me trouble though. Some nights or during some portions of the night it'll mostly move around the upper 60's to upper 70's (like last night), but occasionally drop well below that, sometimes down to zero, or into the mid 30's. Other times it'll struggle to stay in the upper 50's and frequently drop well below that.

I'm trying to pay close attention to the weather to see if I can pinpoint what's changing, and on clear days and nights it seems everything comes in much better, but even on some cloudy days and nights it seems ok.

On the last bad night I had I tried plugging the antenna cord directly into the HD Homerun, and things were pretty close to the same (if slightly worse). I'll try to find some time to do that when the signal is good and see what happens, but I don't think my distribution amp is the problem.

I have, what I think is a pretty powerful antenna for what I'm trying to do, pointed at true north (where the vast majority of stations I'm trying to get are located). Is it possible some of these problems are from getting too strong signals? Generally I'm not getting signal strengths that are crazy high (especially on the channels that aren't coming in so well) Or is it possible that I'm having issues with FM interference? The variability of all of this is what's really maddening.

Roof TV antenna replacement - bad decision?

Hi everyone,
Good news: I have local reception after cutting the corporate cable TV cord and paying a (professional?) technician to reattach some premise wiring and run coax from my roof.

Bad news(?): I let him replace my ancient but probably superior rooftop antenna with the cheapest Chinese product on the market. I figure I got 80$ worth of service from him anyway -- found him on Craiglist -- and I achieved goal of reliable local HD broadcast reception.

My cause for second-guessing include:
- cheapie will break in two at the first 40 kph gust -- its remote rotator does not work; got him to knock off 20$ consequently
- I missed opportunity to reach broadcast 35 mi away in Wash DC and maybe 75 mi from Harrisburg

Basically I'm wondering if I should
- keep the old antenna around for the inevitable day when the new one breaks
- reinstall the old one myself
- have a pro reinstall the old one to ensure it's properly grounded and securely affixed to the pole, which was not replaced
- trash the old one since it's rusty and may fail
- mount the old one on my brick wall as the coolest home decor on the block, and go the rest of my life without a girlfriend

The installer said he couldn't attach new coax to the existing ribbon cable. I understand it might be a challenge, but certainly worth a try giving cost is a 3$ balun transformer. Do you agree?

I'm also concerned about the thin (RG-58?) coax he ran from the roof to the basement. Works fine for now but would older antenna work with same cable? About a 30' run outdoors and another 30' indoors to TV.

FYI, the new antenna received one DC channel 33 mi away until the guy, trying to get the remote rotator to work, repositioned the antenna slightly. I'll try to move it manually to get more from DC but I'm convinced the old one would get DC, probably Harrisburg and maybe Buffalo %^O.

Thanks all! RMO

People can give you some better responses if you can include a link to your TV Fool report (as detailed in the sticky at the top of the forum).

I looked at the HD Homerun website to check out the product. It is interesting, but the lack of a DVR would be a drawback for me. But nonetheless, there are people in this forum that should be able to help you out. There are some pretty smart folks here.

The only other idea I have is to use the tuner in the TV, if you have you have a TV with a tuner, to see if the situation changes.

So I'm actually using the HdHomerun in conjunction with DVR software on my computer (which then feeds over to my AppleTV, it's an odd setup but it works well for us).

I have actually tested on some of the TV tuners I have in the house and they all seem to give me roughly the same to slightly worse results at any given time (it's a little tough to say for sure as as far as I know my TV doesn't give me exact figures for signal quality, just a little 4 bar graphic to give me a rough idea of signal quality, mostly I just look to see if the channel seems to be coming in consistently. The HD Homerun seems to do slightly better than the tuner in the TV I use most often for testing).

By all means do not discard that original antenna. It is indeed far superior to that newer Chinese made product, and it looks like an original Channel Master UHF/VHF combo model which is no longer made. Those UHF diamond elements indicate Channel Master, and they had very good gain. While you may no longer need low VHF, it is still a good antenna. But for a newer replacement antenna, a Winegard 7697 or 7698 would be a better choice. And possibly a Winegard LNA-200 preamp to get distant channels from DC, but be careful with overload from Baltimore.

MHz 30.1-30.6 off air since mid-morning. Don't know about .7-.12 since I can never receive them.

I was watching Russia Today at about 10:15 AM when I embarked to do some business this morning, and it is on now, at full strength. 30.7-30.12 is also performing normally.

If anyone would like to see the, "Propaganda bullhorn that is the state sponsored Russia Today" that John Kerry derided, the video of which that channel plays over and over as a badge of honor, you will get to see the "other side" of Turkey's shooting down of the Russian plane. Some of it is insightful, some is preposterous. As usual.

Short version of Kerry's tirade:
