You are in an area rich with signals. The CM7777 is a fine amplifier but will quite likely be overloaded. Even amplifiers such as the Antennacraft 10G221 or Winegard HDP-269 may have problems with overload despite being designed for higher level input. For local reception, you simply do not need an amplifier... it will cause trouble and provide no enhancement to signal quality.
It looks as if you are very interested in receiving WNPI (PBS). I won't say it's impossible, but it will be a challenge. If you have not purchased an antenna yet, I would suggest the
Antennas Direct 91XG. Don't be surprised if you need the aid of a
commercial quality single channel cavity filter ahead of whatever amplifier you choose. If you do employ such a filter, the output will be limited to a single channel. If you were to pursue such a design, an Antennas Direct
CPA-19 is an excellent low noise amplifier.
WNYF, real CH 18, is going to be an extreme challenge. I do not see the source of co-channel interference listed on your TVF report but the adjacent channel interference from CITY, real CH 17, is going to be like trying to view stars in a telescope aimed a few degrees away from the sun at high noon.
It looks as if CJOH will remain on VHF 13. I doubt that CIII will remain on VHF 6 but I say that only based on the technical motive to abandon the low-VHF band due to the higher noise present there. The folks at
