Often good signal strength with low signal quality is a symptom of interference such as from a local FM station, or having too much amplification in your system (are you using a preamp?) or signals reflecting out an object or terrain and arriving at your antenna out of phase.
Give us as much information as you can regarding your antenna system. A rabbitears.info signal report for your location would be helpful, too.
I'm using a Antennas Direct Clearstream 4V TV Antenna. It is mounted outside, about 20 feet off the ground. There is just a little bit longer than 100 foot coxial cable between the antenna and the Silicon Dust tuner. I'm using a Antra AT-PAA28 Low Noise Pre-Amplifier HDTV Pre-amp Signal Booster with LTE 4G Filter for UHF VHF Antenna Adjustable Gain Excellent for Weak Signal Regions

Sometimes I get WXIA very well and other times it doesn't come in.

The channel that I have the most trouble with is PBS. It often has 100% signal strength, but it frequently doesn't display at all.

The Clearstream 4V antenna is a good antenna for UHF channels, but is minimal for VHF channels unless you are in a strong signal area. Both WXIA and WGTV are VHF channels.

To help the group understand the signal levels at your location, could you do a RabbitEars signal report and post the link here so we can see what the signal strength are in your area? Here is the link to perform the analysis: https://www.rabbitears.info/searchmap.php Just enter your address in the box and press search. Then click move pushpin to center of map view, drag the icon to the position of your antenna, select the antenna height and press go. It will take 20 or 30 seconds to load. At the top of the result list will be a shareable link for the results that you can post here.

So here is my post repack dilemma:
This is data from 8 am. I lose channel 2 from noon until after sunset.

Channel . Signal str. Signal Quality
2 (32) 100 58
5 (27) 100 100
8 (8) 100 81
11 (10) 97 75
14(16) 93 100
17 (31) 88 0
34 (18) 100 95
36 (25) 100 54
46 (19) 100 87
63 (22) 100 0
69 (36) 100 75

I lose 2 until the sun goes down. 17 pretty much never comes in anymore.
36 only works at night.

Locast is now available in Atlanta so that pretty much gives me the channels I need, but it drives up my data usage and I have a 1TB cap with Comcast. Luckily I don't watch 2 or 17 very much, but wife watches some of the ABC shows.

BTW, Locast is a godsend for people who can't install an antenna.

All channels worked reliably for me prior to Repack. I'm hoping that channel 2 will return once they put their transmitter back to it's original location.

Do you guys have any comments or suggestions based on my signal strength?

Thanks again and Happy Holidays!

Thanks for the tip on Locast. I don't pick up WGTV channel 8 here at my location and it does have some documentaries I would like to watch from time to time.

It looks like you have some good signal strengths but poor signal quality on some channels. Since you haven't received much help here about your dilemma, I would suggest you check on the TV Fool 'Help With Reception' forum. There are some very knowledgeable folks there. If you post there, be sure to include links to both your TV Fool signal report as well as your Rabbit Ears signal report and a full description of your antenna system. http://forum.tvfool.com/forumdisplay.php?f=7

Has anyone noticed horizontal black lines flickering across WSB occasionally for the last few weeks? Trying to figure out if it's a WSB issue or a Comcast issue (all other channels are fine).

No, just my usual audio dropouts nowadays from being line of sight liftoff/flyover of the increasing number of traffic, etc., helos stationed across the road at PDK that turns the airwaves into chop suey.

Update:

Been watching either 2.1 and/or 2.2 all week most weeks with only my usual audio issue, but when I switched to watch Castle/2.1 plus overnight movies/2.2 all I got was completely broken up audio/video with still no improvement even after a re-scan.

I thought things might improve once the leaves fell off the trees but it has actually gotten worse.
For some reason yesterday Channel 2 went to a 0% signal strength. Channel remains at 0%. They are Channels 31 and 32.
I've pretty much lost both since the Repack. All other stations remain at good levels.
Still no reply to the email I sent to Channel 2.
I may try to test the antenna outside once the weather improves.

LightTV on 5.4 WAGA - Distorted picture

Has anyone else noticed the distorted picture on Channel 5.4 over the air? They have the aspect ratio flag incorrectly set to 4:3 (rather than 16:9), and I have verified this by looking at the TSReader stream data. I seldom watch this channel, but I hate to see old shows like Green Acres and Mister Ed being squeezed down further to a 1:1 aspect ratio. The other subchannels (5.2, 5.3, 5.5) have the aspect ratio flag set correctly.

Previously sent an email to WAGA (no response after a few weeks), so I just sent an email to Light TV, on the chance they can eventually get it corrected.

Have you tried contacting the Chief of Engineering directly? His name is Jeff Herald. You can also find him on LinkedIn.

Yes, Jeff was one of the recipients on the email I sent to WAGA on November 10th. Never heard anything back. On a brighter note, I DID receive a response to the email I sent to LightTV today, thanking me and saying they would be contacting WAGA "immediately". Will be interesting to see if that gets any attention. It would seem to be such an easy fix to make, with virtually no troubleshooting or hardware to swap out....just that one aspect ratio setting in the PSIP.

WTBS-LP, at display channel 26 and physical channel 30, is not coming in for us today. When my wife complained today about the loss of France24 at 26.4, I assumed another repack phase had happened and rescanned the TV. But it's still not coming up, and the other tuner (a Tivo) shows no signal. Are they having transmitter problems? Can someone with a spectrum analyzer check RF channel 30?

WTBS-26 is owned by Prism, and they also own WANN-32. Prism also owns two stations in Las Vegas, that are problem plagued nearly all the time. Moxie and Oldie Goldies are in and out of blank screen for the past two months here in Vegas. Aspect ratios are incorrectly set on other sub-channels, and the electronic program guide channel has abundant incorrect listings. The owner seems to have taken an unlisted number and e-mail approach to the operation of his stations.

Will the last subscriber leaving Dish Network please turn off the satellite.

Checking on the spectrum analyzer I can confirm there is a carrier present on RF30. But the signal is too weak in Athens to decode it. I used to receive WTBS regularly but since the repack I am seldom able to decode it, even though they are on the same RF channel as before the repack. As others have noted, WANN/WTBS are a real mess from a technical standpoint. Using TSReader to analyze the bitstreams confirms a plethora of mis-configurations...for example, WANN has about 6 megabits of null data in their stream - that's about 33% of completely wasted bandwidth in that channel (RF20).

Thanks for taking a look! I did another rescan and now I have 26-1 "ESTRLA" in the channel list, but my TV says "mode not supported" when I try to display it, and there aren't any other services (i.e. no 26-4). Guess I'll just keep trying occasionally

The signal is strong enough right now to get a decode here in Athens, so I fired up the TSReader software and your TV is NOT the problem. The bitstream is really messed up, with only the ESTRLA descriptor showing up in the channels, and no video content being sent. So yeah, try to rescan occasionally, maybe after a few days/weeks someone there will become aware there is a problem.

I just noticed that 11.1 is mirrored on 11.11. Anyone know why? It’s not SD or SAP. I did notice 11.1 had some weird, non-multiplex, artifacts, like white specks.

Also, http://www.locast.org is live in Atlanta. Basically has every channel broadcasted for the area available on set top boxes like Roku‘s and portable devices such as phones and tablets with as low as five dollars a month donation.

Also here’s an interesting look at ATSC 3.0.

11.11 is identical to 11.1 as far as I can tell so I disabled it in my HTPC.

Locast has been pretty great the few times I used it other than the pop-up nag screen which consistently breaks the connection with my Chromecast. Haven't made a donation yet, perhaps that would eliminate the problem.

Yep, $5/month PayPal eliminates it.

At my location the mirroring is quite helpful since the 11.11 is over UHF (RF25), and is a significantly more stable signal than 11.1 (VHF RF10). Being VHF, 11.1 is more susceptible to weather effects like tropospheric ducting, as well as electrical interference. I suspect that the main driving force was that most OTA antennas are optimized for UHF only, so it gives WXIA a nice boost in their OTA coverage to have 11.11 available.

The only downside is that the video bit rate for 11.11 is about 1/2 that of 11.1 (6 versus 12 megabits) since it has to share the bandwidth with another HD channel (WATL 36.1), but the encoders have gotten so good in recent years the difference is barely discernible to me.

Update on this - I didn't have any luck with emails to the engineer, but I am happy to report that WAGA finally fixed the long standing problem with the distorted picture on LightTV, 5.4. My email directly to LightTV succeeded in getting a response, and after a few back and forth emails they were able to "persuade" WAGA to make the correction to the aspect ratio.

This is another case where contacting the network succeeded, rather than a local affiliate. For mis-configuration problems like channel 5.4 I typically haven't had much luck contacting the local affiliate, since they often ignore emails from viewers,...but the networks do have a vested interest in getting their content (and commercials!) broadcast, so they can sometimes get things fixed. Yay - Mister Ed and Green Acres are now properly displayed in 4:3 format!

Yesterday I decided to finally drop my comcast tv as soon as I can reliably pull in all the networks. I have an unboosted RCA 70 mile range yagi antenna in the attic (about 25 ft above ground) aimed directly at the towers. I live in Marietta - East Cobb. I get a terrific signal from everything I want to see except CBS. The CBS signal is not stable and seems especially bad on Sundays. The picture pixelates and audio drops out frequently on overcast days On a clear day I don't have the problem but on an overcast day CBS is unwatchable.

So here's my question. What can I do that will actually fix this? I don't want to spend a lot of money or make a lot of effort (or both) only to find out that CBS just isn't doable at my location. Putting the antenna on the roof will be a real effort but I can do it if it will solve my issue. A booster might help but amplifying a crappy signal doesn't seem like the solution.

I've read through this thread and see that the CBS signal problem goes way back but didn't see anything that will help me. I would think that they would have fixed it by now.

I see that Marietta is easily within the WGCL 19/46 signal contour area...

Their signal shouldn't be a problem. Using a booster or signal amplifier will only complicate the signal problem you are experiencing.


My first suspicion is you are either having problems with LTE interference (cell tower) or possibly an FM tower nearby, but that's unlikely because it would affect other channels. You should look around your immediate area and get familiar with any towers that could be cell-phone towers or an FM tower. It might take an LTE filter on the coax cable. The first culprit would be LTE interference, which is from a UHF frequency, such as T-Mobile using 39-41 UHF frequencies, or the others that are at channel 58 and above.

Antennas - Antennacraft MXU59 UHF antenna & home-brew version of Antennacraft VHF Y-10-7-13 antenna @ 25'. Both antennas fed through a Channel Master 7777 30dB pre-amp.
Tuners - Zenith DTT901 converter box; AirSpy HF+ sdr; Silicon Dust HDHomerun Dual ATSC tuner, using Rabbitears autologger support.

Thanks Jim. I'm an Engineer and usually good with projects like this but I'm not knowledgeable about antennas and that sort of thing. Are you suggesting that I buy an LTE filter and try it? There are cell towers all around me so interference is a distinct possibility. I guess I'm asking for some more clarity on your suggestion because I don't completely understand what you are suggesting. Is there a website that will tell me where the cell towers are and if so how does that help me? Thanks for responding - I appreciate it.

Can you post a link to your rabbitears.info signal report for your address so we can see what your signal levels look like? It would be very helpful for this discussion. https://www.rabbitears.info/searchmap.php

WGCL (CBS) broadcasts from the same tower as WUVG, WPCH, WUPA and WATL. Are you getting good signals from those stations???

The first thing I think about when you say East Cobb is trees--lots of trees. Trees can interfere with UHF TV reception. I am a few more miles away (Acworth) and get some occasional glitches due to tree foliage.

An LTE filter is not expensive and certainly worth a try. The ChannelMaster LTE filter is about $20 on Amazon. Try to stick with major brands, some of the less expensive filters may be for the European bands which are a bit different than here.

You will always get stronger signals with your antenna mounted on the roof than you will with it mounted in the attic. Also, with it mounted in the attic, other metallic objects, wires, metal or foil heating ducts, etc can interfere with reception. If your signal is on the borderline, moving the antenna to the roof may be just what is needed.

Also, I have seen instances of other electrical equipment interfering with TV reception, sometimes just on 1 or 2 channels. Things such as LED floodlights, power supplies for LED undercabinet lighting, power supplies for laptop computers, etc.

Another good place to ask for advice is the Help With Reception forum on TVFool.com http://forum.tvfool.com/forumdisplay.php?f=7
There are some gurus on that forum who are real pros when it comes down to identifying and correcting reception problems. If you post on that forum, be sure to link you RabbitEars signal report and a good description of your antenna system (make/model of antenna, lengths of coax,
splitters, number of TVs, etc.)

You are right on target about the amplifier. If you don't have good signals to begin with, you will just be amplifying garbage. Amplifiers are good when you need to overcome long lengths of coax between your antenna and TV set(s)
