I had a big long reply typed out, but my log in timed out and I lost it all, man I hate that. lol

Anyway long story short;

Before you buy anything, get up on the roof, use as short a piece of cable as you can that runs to just one TV. Move the antenna around in different places on the roof. Don't forget to change the up and down direction as well. Sometimes just a few feet can make a big difference.

That dish j pole may not be the best place for your antenna. Based on your report those signals should be popping in clear as a bell.

Generally speaking, (there are exceptions), but you normally want your antenna as high up as you can and facing the towers with no or few obstructions between your antenna and the towers. Trees are the number one thing that blocks UHF signals for most people. You have seen this with the loss of stations when the leaves came out, it will get worse.

Only after you have gone through this trial and error exercise and located your antenna in the best place you have, then start thinking about a bigger antenna or distribution amp, better cable, better splitter setup, etc.

Looking at the Longley-Rice information at rabbitears.info for your area, it seems to me that the quality of reception at your house will depend on your exact location and height of your antenna, of course. It appears to vary by station because of the terrain; stronger or weaker.

You could send a PM to rabbit73 and I'm sure he could check your area out and graphically show you what would be optimal at your location; your privacy would not be compromised but you could get more definite answers to your issues. Or, take up ADTech on his offer to help you offline as well. He would also give you excellent help, I'm sure. And Tower Guy, rickbb, JoeAZ and Bobsgarage, are all experienced Techs who are offering clear advice. I'm just the piano player here on this forum.

Good luck to you and I look forward to resolutions to your issues!

just a different thought.

Since the reception seems to change when antenna position adjusted, and different in different rooms etc it could also be a bad connection or a bad piece of coax in the run etc. or bad splitter. I suggest , like rickbb did but for a different reason that you run one coax directly from a single tv to the antenna. Try to make sure all connections are tight etc. This should be the best you can do with that antenna in that location . Might try moving coax a little and see if signal changes. Next would be different antenna location. Also you might ask friends or neighbors in the area what their reception is like and you can often see what antennas are being utilized in the area just by driving around.

Second, pics are generally helpful and certainly can't hurt. Would like to see pics of trees at about 164 degrees preferably from roof near antenna location and antenna installation.
