I wish there was antenna maker would make antennas like yours. very efficient and rugged and made to last. go giants buddy!
I'm too close to the local stations for a preamp. Sutro Tower is just 3/4 mile away from our home. I've tried several different brands, but they are all overloaded by the strong local signals.

The yagi shown in the photo is an Antennacraft Y-10-7-13. It's still made and sold at many electronic parts and antenna stores like Solid Signal, Stark, Summit and Warren for about $40 to $45.

Yeah... Go Giants, for sure!!

I have noticed, just within the past several weeks, that I am now having a very similar issue on many (but not all) shows on the Investigation Discovery channel. The difference is these programs don't have background music/sound effects that have the reverb echo distortion like a cave thing. I can rewind the show and have verified the level of the center channel dialog is in the file (it's not my surround system faltering).
I have the same issue. All of the background sound are too loud and very distorted. I've watched the same shows On Demand and can confirm the On Demand sounds perfect while the signal from KXTV are incredibly distorted. It's been this way for years and I thought it was a problem with my system. I finally compared against On Demand it the difference is night and day.

I've never watched on demand (because I use WMC PC). All I can say is, the audio on KXTV (ABC primetime shows) BITES. It sounds like everything is in an echo chamber or run through a reverb processor.

The audio almost sounds like it's encoded at a very low bit rate. The first time I noticed it was during Revenge. I thought it was deliberate to match the dissonance of the show.

Now I want to watch the series over again to hear what I was missing.

The engineer at KXTV must think that on shows like Castle the background music is more important than the spoken dialog. During these moments I try my best at employing dog ears.

I only have stereo for my TV audio and I haven't had a chance to perform this test on an evening network program, but today on the football game I was able to switch rapidly between KXTV, KGO and KSBW. The audio on KGO and KSBW sounded identical but the KXTV audio sounds like the high frequency response is slightly rolled off. It doesn't have the crispness heard on the other two stations.

I suppose this doesn't mean anything but KXTV is a few seconds ahead in time compared to KGO which is a few seconds ahead of KSBW.

It's gonna be tough doing any kind of test/comparison just using stereo speakers.

I've only heard the KXTV audio problems on prime time shows like- Castle, 20/20, Motive, Revenge, What Would You Do, Forever.

Never heard problems on local news, Jimmy Kimmel, Good Morning America, (nightly) ABC World News. In fact the Jimmy Kimmel musical acts sound really great.

Also noticed some prime time shows DON'T have the audio problem, like - How to Get Away with Murder, Agents of Shield.

I've tried bringing this up in a National ABC topic but it always gets dismissed or ignored...

What happened?

Edit: Back to the main antenna at 8:30 am.
Chuck,

We lost two of our three amplifiers at the main site. Switched to the backup. Sorry, late in reading this.
