AdTech,
First off thanks for your suggestions. I thought I'd post an update after I changed a few things per your suggestions:
1. I reconnected the RCA 751 to the VHF input on the pre-amp.
2. I connected the DB8 to the UHF input on the pre-amp.
3. I removed the secondary distribution amplifier from the system.
4. I re-aimed my antennas.
Results - almost perfect! Thank you so much for your help.
I am receiving very strong signals on all but one channel that are in the yellow band of my TVFool report. Unfortunately it is KQCA MyN, one of my wife's favorite stations to watch comedy sitcom re-runs in the early evening.
However for me... I am now picking up a very strong signal for all the major networks which was fantastic for football this weekend.
Curious thing is... when I was aiming the UHF antenna (DB8) I was getting such a strong signal on all the other channels I decided to use 58.1 (KQCA) as my fine-tuning target to see if I could get a better signal on it without loosing any other channels. During the tuning the best signal strength for 58 was waaaaay north of the tower direction... which I found very odd.
If I tuned to that far north direction I lost the other channels but 58 came in clear and strong. I suspect something was making the transmission from 58 bounce to such a degree that I had to point the antenna so far north to pick it up. A tree perhaps?
I had to move it back to the best direction (91-94 deg.) for the majority of stations to come in clearly.
In any case... by that night 58 came in strong enough to be to watch her shows without too much break-ups. So I suspect that is going to be the best I can get at this location unless you have any other suggestions.
