For what it's worth, I live intown and WXIA's signal strength has dropped dramatically for me too recently.
post #2672 of 3205
To echo and expand on what's been said, your DB4 is UHF only, but your coathanger is, uh, wideband, and apparently passed enough VHF to give you WXIA. Or maybe there's been a signal power power drop like brownieland said above.

Combining antennas in the same band is a bad thing to do, electronically, because it wreaks havoc on your pattern. But you can combine antennas in different bands no problem, as long as you're sure that each antenna doesn't cover the other antenna's band at all. So get a VHF antenna (try rabbit ears for starters, with no loop or bowtie) and a VHF/UHF combiner, and hook it all up with your DB4 and see what you get. I have a big VHF array aimed right at Stone Mountain for WGTV and combined with my DB2 for getting everything else. (WXIA is less than a mile from me and I could get it on a paper clip)

Right. You don't get WXIA with DB4 because DB4 is a so much better antenna than a homemade coat hanger thing. It is undesirable for an UHF antenna to pass any VHF, cause it makes it susceptible to VHF noise. Your coat hanger antenna almost for sure had a poor frequency response, blocking some frequencies it should have passed and passing some frequencies it should have blocked.

Defending the "coat hanger thing". Just for fun I built one of those coat hanger antennas to pick up the Carolina channels, which it did... including
dt13 68 miles away. I didn't see any vhf noise, just a perfect picture. My "real" antenna is a channel master uhf 4228 that receives 26 channels from the Carolinas including dt 7, dt 9 and dt 13, I beleive that is a good thing, no vhf antenna needed. Is there a difference in vhf noise received by a uhf antenna vs noise received via a vhf antenna? In most cases these two signals are combined into one, before the tv set. vhf stations are more susceptible to noise, but I doubt the antenna has anything to do with it....Just another opinion....

Can you elaborate on this?

The (newer) DB4's balun is specifically designed to admit VHF from the feed line...

Your statement doesn't make any sense.

Is the TVGOS data via WPBA continuing to work for those of you who need it for your devices?

So far, so good. Just waiting for Comcast to get their equipment up and running so my girfriend can get her feed. She is out in Woodstock and I am not sure if she can pick up WPBA ota, plus we have no way to feed an antenna signal to her Pioneer in the basement without running cable down the side of the house.

I have had no problem getting WXIA using a DB4 in my attic. It is not even pointed toward their towers. Even using a Clearstream 1, I have no problems with it and it is uhf as well.

In the far northeast channel 11 is now the low man on the totem pole. WSB's recent improvements has put their NIGHT time signal on the level with 5, 17, 46, & 69. Channel 2 is still effected by atmospheric conditions, but they usually settle in at night and will continue until 7 in the morning. I really thought that 11 would be one of my stronger ota signals, that has not happened. I have a winegard ya 1317 about 30 ft above ground, just for their high vhf, but their signal is constant break up.
My signals normally change along with the change of the seasons, the falling of the leaves have improved some channels and others get weaker.
Channel 11's signal has gotten worse in the last couple of weeks. It could be them, or it could be the season.

For some reason, the WPCH HD channel on comcast switches to colorbars every night at 1am. Anyone know something about this?

The comcast rep was clueless and decided to send out a technician to check on it, which is idiotic on so many levels....

I'm saying that your coax cable IS the VHF receiving element for the DB4 (and the C1/C2).

If you don't believe it, place the coax inside a metal tube to prevent RF from getting to the cable and watch your VHF stations go away.

There was a design change a while back in the balun when they went from a traditional-style matching transformer to the current PCB balun.

Well if that was true about the coax, then I wasted money on the antenna. I can not pickup anything with just the coax and no antenna. I have never seen that with coax, maybe with flat ribbon. I am not using any of the new PCB baluns so this is not an issue for me. If that is the case for others, then get the old style. WXIA is on the high end of VHF, close to UHF so most good UHF antennas will pick it up. Has anyone had their signal analyzed to see exactly what their received signal is showing for WXIA?
Michael
NOt sure what is in the Clearstream 1 since it is all one unit, no separate balun. But still, I know that if I disconnect the antenna, the coax does not pick up anything.

I live in West Cobb. WXIA signal dropped recently from 98-100% to 86%. It is very steady, no problems. It is not my antenna since GPT (8) is unchanged at 93% and steady. Anyone know why?

I've been unable to populate the listing data from TVGOS through Comcast. One of our sets with built in TVGOS is hooked directly to cable (no box) - I've got the channel lineup (from when it worked previously) but since the switchover it doesn't show any listing data. The setup screen says it is searching.

Any tips for fixing this?

WIRE-CA, the low powered TV station in Atlanta, has started broadcasting in digital on its former analog channel 40. The digital signal is multiplexed into 4 streams (labeled as WIRE-D1, WIRE-D2, WIRE-D3, and WIRE-D4). All of the four digital sub-channels were carrying different infomercial programming as of Sunday, Oct. 11. The station has filed with the FCC to make the flash-cut to digital on its former analog channel 40 and its official call sign will be changed to WIRE-CD.

With the analog signal of WIRE shutting down, that leaves only two (low powered) analog TV stations on the air in the Atlanta area - W23DN (on ch. 23) and WDTA-LP (on ch. 53).

Rovi said that they are installing equipment at Comcast to supply the TVGOS. OTA it is on 30.1 which has been working since about the 5th. They said it should take about two weeks from that time for cable. Comcast already has changed 97 over to WPBA 30 for the TVGOS channel. Just waiting until they get it turned on. Hope it will be soon.

Thanks for this info; I've updated the table in my link below.

FYI if anyone's interested, OTA RF channel 55 nationwide is in the process of getting licensed to Qualcomm for TV distribution to handhelds. The MediaFLO mobile TV service is available to AT&T subscribers as AT&T Mobile TV and to Verizon Wireless customers as VCAST Mobile TV. Note that channels 52 through 69 were cleared out as part of the TV transition this year (excepting a couple remaining low power stations) . As I understand it, this was running on channel 55 before but is now expanding greatly with the UHF space opening up. There are 30+ licensed transmitters in Atlanta alone (operating as an SFN, see wikipedia page for explanation).

...and don't forget that these distributed UHF-55 transmitters, at around 50kW each, represent a hidden potential for overloading pre-amps and tuners for unsuspecting folks as discussed in another thread.

WYGA-LD, the low power broadcast digital TV station in Atlanta, currently broadcasting on channel 16 (from the WUPA-TV tower at I-20 and Memorial Drive) has changed the programming on the only active sub-channel 16.2. It is now carrying the AMGTV network. It apparently dropped carrying the White Springs TV after that network went off the air. In fact, WYGA-LD was just broadcasting a "No Signal" message for a couple of weeks on 16.2 until it picked up AMGTV. The AMGTV network feed seems a bit cleaner and does not suffer from the feed quality issues when it was carrying White Springs TV.

Also, WYGA-LD's 16.1 channel does not seem to be active anymore (at least my LG tuner does not decode it). The other multiplexed channels, 16.2, 16.3 and 16.4, do work though 16.3 and 16.4 just display a black screen.

More changes may be coming to WYGA-LD as they have applied to the FCC to change its broadcast frequency to channel 18.

Anyone with strait OTA figured out how to watch the Falcons game Monday? I don't think its on ESPN360. justintv maybe? I will never go back to cable tv so ESPN and Comcast can go pound sand.

Nice.... thanks for the heads up. I set up PlayOn with my XBox which should come in handy in the future.
post #2695 of 3205
Yep....I can't remember any Falcons games not being shown locally (regardless of main carrier) since they sucked bad and had blackouts.
post #2696 of 3205
Has something happened or changed on channel 69? For about the last week it's been gone for me. I had it solid before then and it just went away. I looked it up and I believe it's broadcast on UHF 43. I did a manual add and I can see a signal but it's barely there now. Is it just me or did something change?
post #2697 of 3205
It's there for me right now. I did notice a few days ago (around 11pm) that they were in black, while channel surfing by it, but otherwise I wouldn't really notice. Even if they did have shows I would watch, the ludicrous grey side panels would drive me away.

RF channel info is in the link in my sig.
post #2698 of 3205
Seems like WSB and RTV (WSB sub channel) are still cutting in and out. What gives? When will they stabilize their signal strength?
post #2699 of 3205
I have been having problems with channel 69 for a couple of weeks. Sometimes the signal is strong, other times it is pixelating. I know my antenna is not moving because it is securely mounted in the attic. Not sure what is up with 69.

I did a rescan on my TV today, first time in a year or so, and I'm picking up WANN pretty much perfectly. Currently it's 4 subchannels (all with active video) as 32.1 - 32.4, on RF channel 29. I wonder why they've bothered with the 32 branding. I've updated the table in my sig.

WSB is glitchy for me too. Anyone heard anything from/about them?
