No, I truly believe that he wants to help and is thoroughly disgusted with how far we've gone from people having enough basic information to work with. He's been trying to get people to focus on first principles and build from there. To put a bow on this drift, think about what you heard, or did not hear, from anybody - local affiliates, manufacturers, the FCC, etc. - concerning the move to digital TV. It was as if no one wanted to say anything that could bias the market from any solution, whether it worked or not.

Let's get back to the task at hand here. To recap:

1) the TVFool report showed tremendously strong signals and a clear view (terrain-wise) of the transmitting site.

2) several channels were dropping out - it just so happens that one is his strongest

3) adding a pre-amp didn't help

4) the signal gets split a couple of times along the way

Two things initially were in play - overloading the tuner and multipath reception conditions. We suggested "desesitizing" by first aiming the antenna off-target a little (which could solve multipath, too) then second adding a splitter to the line to knock the signal down some. Turns out there were already splitters in the line, and with multiple splitters, the inevitable signal reflections (something a layman would not know about) could cause problems.

The next step is to go to the least complicated configuration and build from there.
