Thanks to all who took the time to contribute to this thread!
At last, I have a complete channel lineup.
There are two key things that got this antenna install working fully.
First is the FM filter. I now have two back to back. Inserted one, and saw symbols on the VHF channel. Insert two and the signal improved more but still not usable.
This also corrected some pixelation I had on the channels that were being received.
That result prompted me to get a new length of coax and return the mast and antennas to the original testing position on the garage.
While I did get signal and a picture there, the absolute peak of the house was 20 feet horizontal and 10 feet vertical away.
We went along the peak while watching Signal GH on my phone. Even better results up there. This also reinforced the location, location, location comment I had earlier. If I moved 2 feet in either direction along the peak, the signal took a 15% hit.
Located the rafters, put the pitch strips on the tripod feet and lagged it into place. Mounted the mast/antennas and found the signal had increased 10% more just because it is a wee bit higher than when my wife was holding it. Or possibly because it was now stable.
In all, I guess the signal could be a bit better if not for the trees, but that's one of the things we love about our house.
There is not a chance I would have pursued this project this far/long without all of you helping out. Not a chance. With your expertise, it was time consuming, but in the end, rewarding.
The picture quality over the cable box is day and night, my wife loves it. That alone is payoff to me.
Still need to dress in the coax to tidy it up, and there's the holes to be properly patched where the tripod used to be. But in all, a good day's work.
Thanks again, it is greatly appreciated!
