Back in late 2001/early 2002 I installed a CM 4221 on a chimney mast about 20 feet in the air for the sole purpose of getting high definition TV over-the-air. I pretty much got all the local stations without any problems, but it seems I've always had occasional pixellation on KOMODT (38-1). Nonetheless, it was relatively inconsequential due to being a Comcast customer and getting that channel copy-free from the time they added it to their lineup.
Well, just last month Comcast in all their brilliance decided to start charging us a $10/outlet fee for all our CableCARD using devices (4X - 3 TiVos and 1 HDHomeRun Prime), and I am now strongly motivated to "cut-the-cord". In order to do that, I really want to make sure we can get all our local channels without issues.
I'm pretty happy with our reception of all the channels, but KOMODT is probably the one we watch the most, and it is also the one I have problems with. We get a consistent signal strength of 100 on HDHomerun Signal Meter, but the signal quality is normally hovering around 65-74 for just that channel while being at a 90 or higher for all the other channels.
I'm willing to put up a different antenna or move it to another location or pre-amp it (right now the only amp I have on the line is a Channel Master PCT-MA2-4P just prior to splitting it), but I'm hopeful that someone will be able to suggest what troubleshooting steps I should take and/or what different approaches might provide better results.
BTW, here's my signal map:

Also, I should add that my antenna has never been "aimed" with a compass, but kinda eye-balled at where it seems the signals are best. The neighbor to the south of us have two huge maple trees that seem to be between our antenna location and the direct it perhaps "should" be pointing, but I've tweaked it more toward the opening in the sky toward the southwest.
Thanks!
