I looked at the transmitter signal strength plots for KSBW and KCBA and unless you're on top of a hill in the city with a clear view to the southeast, it's unlikely you'd ever receive them. The signals are very weak even in a good spot. With the adjacent channel interference you must be getting from KGO and KNTV that makes it even more impossible to receive them. Maybe that's why KDTS isn't so good at your location.

I have been receiving KSBW, on and off, for a month here in Rohnert Park. In fact, I am receiving them right now, with a 4228..... It's mind blowing, considering how far away they are. In perspective, I also received KNTV 11 when they were coming from San Jose better than I get it now from Mt. San Bruno...
post #8853 of 10423
You're probably in a hot spot. There are some up in your area for stations to the southeast plus you probably have much less adjacent channel interference than anyone in SF does.

Fremont Peak to Rohnert Park must be about 140 to 150 miles. Receiving channel 8 on a CM4228 at that distance is amazing! You must have a wide open clear shot right down the Bay.

Wow! Signals this afternoon were about the strongest I've ever seen coming from Walnut Grove. All of the stations, both VHF and UHF, were coming in at way above average levels up in the 25 to 27 dB range.

Sutro Tower TV and one FM station will be using Auxiliary Antennas this week!

 

 

 

You are getting this message because you requested notification of Auxiliary antenna operation at Sutro Tower.

 

Sutro Tower will be conducting routine maintenance on the top of the tower this week. Therefore, all of the TV stations and KOIT (FM) will be using Aux antennas. Below are the days and times involved:

 

Tuesday, September 11—9 AM to 4 PM

 

Wednesday, September 12—9 AM to 4 PM

 

Thursday, September 13—9 AM to 4 PM

 

Since analog TV operations ceased at Sutro Tower in 2009, there is very little difference between the measured radio frequency emission levels in the neighborhood between Main and Aux antennas.

 

Thanks,

 

Eric Dausman

Vice President & General Manager

Sutro Tower, Inc.

1 La Avanzada Street

San Francisco, CA 94131

Thanks for the heads up. I was watching KGO this morning at 9 am to see what happened and it went from SNR 23 dB (better than average) to 17 dB when they switched antennas. KQED was still coming in fine but KBCW disappeared which is usually the strongest Sutro UHF station. KTVU, KRON and KCSM were all teetering on the cliff which is not the normal situation when KBCW is not coming in. Usually KBCW has to be very strong to see those 3 stations.

Without the CATV stamp, the cable is leaky.
Leaky means the cable itself leaks signal in & out even without the antenna attached.
At the antenna,.... If you cut the cable with tin snips. All channels / signals should be zero / no signal.
If you get stations with the cable attached & no antenna connected, signal is leaking in. (Not good)
If stamped "Foam Coax Assemblies" (Radio Shack) .......junk it.
If stamped "RG-59 CATV" UL Listed ...... Ok ... but not the best. (San Jose's A/B Cable tv system) "Ok" for tv antenna only. ..... "Not ok" for modern cable tv internet. " Not ok" for Dish antenna systems
Thin coax cables that come with new VCR's for jumpers ..... Junk
Only one bad cable ..... can leak signal into the entire cable system.
OK, didn't see this post when you addressed this (quoted above) on July 24, 2012, post 8768 in this thread.

I have my 500' roll of cable on my lap (somewhat diminished, but I think I have more than half the roll left, it's white). I am almost positive I bought it a Home Depot. I will type exactly what it says on the cable, I think it might indeed be RG-6 CATV UL Listed, but that's not exactly what it says. It says:

CAROL(R) C5775 RG6/U 75 OHM COAX--18 AWG 75C SWEPT 10 2.3 GHZ EE60233-8 CL2--CATV--CM (UL) 000052899 09-04


What do you think? Is this good quality cable, good enough to use on a couple of new Weingard HD7694P antennas? I figure to order them today or tomorrow, wonder if I also need cable.

Um, one other question. Is it likely I'll get acceptable FM signals from one of those antennas?

That cable should be fine, and yes it is stamped CATV (UL)
Also 09-04 could be a date code September 2004 ... for example.

No, FM is near VHF channel 6, that is in the Low-VHF band, not covered by the HD769X series of antennas. Winegard 8200 covers FM band, and all antenna models generally with 4 foot+ elements. Also rabbit ears (Fully Extended) to something around 4 feet each.
You can build one yourself (Google FM Dipole Antenna) DIY with good signal capture results.
You can also purchase a FM antenna for that purpose.

Ah, thank you. I think I'll order one 7694 Weingard and a different antenna (HD and FM) for the other, which will be pointed about 90 degrees counter clockwise to the 7694. I'll split the HD+FM antenna and send one branch to my AV receiver in hopes that I'll pick up some distant FM stations. The TV branch will go to one of the two inputs on my MyHD HDTV card, to pick up some extra stations in the south bay.

I checked out my reception (%) today on my HD stations, and among Fox 2 (KTVU), KRON (channel 4), KCBS channel 5, KGO TV7, KNBR TV11 (NBC), only channel 11 is getting 100%. Channel 7 is better now, around 56%. I am getting 0% consistently on Channel 4, KRON! I suppose the antenna is just very corroded. It has been on my roof for about 20 years.

KQED was just granted a construction permit to increase power from 710 KW to 1000 KW or an increase of 1.5 dB.

No word on when that might happen.

Winegard HD-7080P High Definition VHF/UHF/FM TV Antenna (HD7080P)
appears to have VHF UHF FM HD capabilities, at 1/2 the price of the 8200. I'm thinking get one of those and a 7694.

Should I replace the RG-6 I'm using? Maybe just chop off a few inches from the end?
post #8863 of 10423
That Winegard is very similar to the one that I've had for about 30 years (Chromstar 2000 series, model CA-8100). It's been in continual use before, during, and after the digital switch. I used RG-6 cable (don't remember if it was UL listed and labeled as CATV or not, probably is). I separate the FM signal with a Winegard signal separator and run that to the stereo in the house with old coax (RG-54?). The antenna sits about 30' from ground level. HDTV has always been trouble-free and FM is always clear and clean (at least for the stations we listen to). We get everything from Sutro and San Bruno.

It's your call...
The tool for attaching the connectors is expensive.... $$ ... The connectors themselves are pricey. Plus the cable stripping tool. An easy $50 to 75 for tools plus connectors.
Unless you already own them. (Or have a friend / neighbor that works for dish/cable company) something to keep in mind.
I think I paid around $20 just for the small plastic jar full of cable connectors. (The same ones the cable company uses)

I would not use the connectors that are "hand"-push on or twist on.eek.gif Those are bad news. (Usually sold at drugstores, ETC)

The specs on that model ... you linked
"2.8 db gain over reference dipole." ......... In the channel 6/FM column.
Kinda weak specs for FM. and/or channel 6
Model HD8200 has a reported gain of 6+db in the FM (Double the Signal Gain)
With the HD8200 ...... You get what you pay for.
.............the reference dipole can be built DIY.

the same thing for FM, but made for 88-108MHz

OK, thank you, FM's important to me. I've wanted to get a clean signal from 89.7 Los Altos Hills for many years. Funny thing is I pretty much do in my car (!) but don't in the house. mad.gif No, I haven't tried everything. I think I'm going to get that 8200, also a 7694 for TV from Sutro. I have two masts on the roof, at least 15' apart.

Do I need a special signal splitter? I have a few, had for many years. I assume some are better than others. I guess I could get something thrown in with my order at solidsignal.com. I bought the ones I have a Home Depot, paying attention to the specs stamped on the side, probably around 2004-5, trying to get ones with the least purported signal loss.

I have crimpers and connectors, not sure how good the connectors are, I have a collection. Maybe I should order some more, won't need a lot. Do I need a cable stripping tool? Can't I do it with just a razor blade if I'm careful?

Can I use the RG-6 I have out there on the roof? Maybe trim off 3" or so from the end, in case moisture has crept in there, it's been out there maybe 7-8 years.

IIRC, my RG-6 comes into the house through a hole in the wall and I have a splitter in the attic that sends branches to (1) my home theater room and (2) to my bedroom, where I have an old analog TV and converter box (I rarely use those!). I might need a few more splitters, I imagine, if the ones I have aren't up to snuff.

The 8200 UHF-VHF-FM antenna is a bit overkill for just FM. Did you look at the specs ?. THE Antenna SIZE in total feet ? The UHF elements alone-- are a few feet long. A standalone outdoor FM yagi antenna would work just as well.

Simple non amplified tv rabbit ears fully extended in a V pattern should work near a window. Or a home made dipole gives impressive results. For a lot less dough. $$

Big Box store indoor tv & fm antennas contain low-quality noisy amplifiers that create problems and give so-so chance results.
Sadly, they are sold for merchant profit..... not quality end-user results.

Dont't be fooled by DIY antennas made with simple copper wire materials. They do work.
BTW..... a car radio antenna is simply a copper strip glued to the windshield (sometimes part of the rear window defroster wires.) (Honda Accord models)
or some other basic type. (Hidden)
post #8868 of 10423
Buying an 8200 for FM isn't just overkill, it's insane It's 10 wide and 14' long!

If you want locals plus FM, a small all-channel combo is all you need. The antennas cover channels 2-6 also covers FM since FM is immediately adjacent to channel 6. The largest dedicated FM antenna that comes to mind is a 6-element from Winegard. Antennas Direct sells a 3-element FM antenna.
post #8869 of 10423
I was thinking of using the 8200 for HDTV + FM.

Actually, here's my situation:

I'm line of site to Sutro Tower, maybe 15 miles away. I'm in the Berkeley flatlands, a two story house, so there are no structures between me and Sutro Tower. I have two antenna masts on the roof, about 15-20 feet apart (had the roofers install them when I had a roof replacement around 5 years ago). My MyHD HDTV cards (I'm using a MyHD 120, but have a 130 I'll swap it with), have 2 antenna inputs. I used to use both antenna inputs on the one card I can have in the computer, one input with my 20 year old Winegard pointing at Sutro Tower, the other input was connected to some TV antenna I found, that I pointed ~90 degrees counter clockwise from the Winegard antenna, basically pointing to the south bay, which I used to use to pick up some extra stations, for instance TV 36, KCSM 60, KQED, the PBS station, channel 54. One of the antenna connections on the MyHD card broke, so for the last few years I'm just using the Winegard antenna pointing at Sutro Tower and picking up the main network stations, foregoing all the south bay stuff. I bought a used MyHD 130 card, not so much for the cable capability (I only do OTA), but to have a card installed that has both antenna inputs functional. I haven't gotten around to installing it in place of the MyHD 120, which has only one working antenna input.

I want to pick up 89.7FM, which broadcasts from the south bay, Los Altos Hills. That's why I want an antenna on the second mast that picks up FM as well as HDTV (Of course, besides picking up 89.7 Los Altos Hills, it would be nice if I could pick up a wide array of other FM stations!). On the first mast I will have a Winegard 7694 pointed at Sutro Tower, for the main network stations.

I only have two masts on the roof. How can I set things up so I get south bay TV and FM? I only thought the 8200 was a good choice because it seemed like it would solve that problem. Is there a cheaper, smarter way to do this?

I've built a number of rabbit ears antennas over the years for FM. I just take a standard dipole antenna and mount it on contraptions I've made from wood sticks with a wood base, which is held together with wingnuts, so I can adjust the rabbit ears any way that seems to work best. They seem to work OK for most stations, especially if I reorient them, but for weak distant stations, not so much. Well, I have one on my refrigerator. It would probably work better if near a window as you say, but a window pointing toward the south bay is not to be found in my kitchen! The kitchen is downstairs, naturally, which makes it tougher. I figure I can somehow get an antenna that's near or on the roof connected into the kitchen.

If necessary, I can install a 3rd antenna mast on my roof, but it would be a bunch of work. I got some extra roof tiles from the roofers, and they're stored in the garage.

I believe you're a lot closer to their transmitter than I am here in Berkeley.
- - - -
OK, absent any further suggestions, comments, guidance, I'm ordering:


Winegard HD-7082P High Definition VHF/UHF/FM TV Antenna (HD7082P
for pointing south to get the TV stations from that direction, plus FM. It's cheaper than the 8200u, actually has a higher spec than the 8200u at channel 6 (6.2db over reference dipole compared to 6.0). It's somewhat smaller too.


Winegard HD 7694P High Definition VHF/UHF HDHD769 Series TV Antenna (HD7694P)
for Sutro Tower TV, pointing west.

Getting a couple of Weingard splitters, 2 and 4 way.

Do I need a stripper? Can't I use a razor blade? If not, I can probably borrow one from the Berkeley Tool Lending Library.

Strange stuff for me in the north bay tonight. Losing fox, which never happens. Yet nbc is showing full strength. Its usually the opposite.
I still am amazed how signals vary so much throughout the year.
post #8874 of 10423
I'm experiencing very bad conditions this afternoon with nearly all signals from everywhere way down with many not coming in at all. If it wasn't for my two local stations 19 and 28 which are normal, I'd think my antennas were broken. I checked the temperatures around the area and it is about 10 degrees warmer up here than down in the valley. Apparently there is a strong temperature inversion which is unusual for the afternoon. I've been having a lot of trouble at night too when it's been mostly in the 70's all night long.

post #8875 of 10423
These atmospheric conditions can indeed be screwy at times. What gets me is when your normally strong 50 mile stations are wiped out, but your occaisonal 85 mile stations are blasting in at 100%. I don't quite understand why these weak, distant stations are so strong, but the closer in stations have disappeared. Looks like the closer stations would be strong as well, unless they are getting too much signal that is overpowering the tuner or creating multipath. That's all I can figure. But I do have one strong 75 mile station that never disappears, only sometimes a reduction in signal strength when these type of conditions prevail. Normally 100% on WBTV3 RF23 from Charlotte, a 1000kw top mounted UHF omnidirectional signal. 2000ft tower. They did a great job with their digital conversion.

Signals continue to be unpredictable here in San Francisco. During the past week they've been normal, below normal and above normal... in other words, all over the place. The VHF stations from Walnut Grove have been doing a better job than the UHF stations, but all have been up and down.

You're seeing the same thing on the San Francisco area stations as I've noticed lately on the Walnut Grove - Sacramento/Stockton stations. The VHF stations seem to be up, while the UHF stations are down more so than the other way.

Hi,

Attached are two channels received here in the SF Bay area.

Look at ION (KKPX), eight sub-channels are encrypted. Most DTV sets will not
even say they are present.

But KAXT's twenty channels can be received by all DTV sets.

My Dish Network ViP 722 DVR crashed and wouldn't reboot, so they sent me a new replacement receiver.

When I scanned in local channels on the new receiver I received several sub-channels in the list that are encrypted or do not show any picture. The encrypted ones do not show up on my Sony and Panasonic receivers. The channels are:

KQED 9.8 and 9.9 (RF 30.8 and 30.9)

KOFY 20.5 (RF 19.5)

KKPX 65.44, 65.45, 65.46, 65.100, 65.101, 65.200, 65.201, 65.209 (All RF 41)

KFSF 66.72, 66.73 and 66.81 (All RF 34)

These encrypted channels, I suspect, are all for the mobile TV service.

My Channel Master #7000 (Set top box) crashed a few months ago...... People are reporting online that this STB is defective with bad capacitors on the power side of the board. What a POS. Lasted only 2.5 years.
This box was on 24/7 with the power saver disabled. They are ALL bad, and all these boxes will soon fail...... (Check what people are saying online -google)

Must have capacitors from the same company.eek.gif ( China)
Channel Master has no repair facility, and offers no service on the matter..... Who has time for this ? .... Order parts online,... open box,... unsolder,... resolder,... etc.
You basically need to replace ALL the capacitors with new ones... (Quality ones made in Japan)
Thank goodness I have extra boxes floating around here.... In 2009,... I asked everyone on cable to "give me"wink.gif their unused government STB coupons.
