The CM-7777 in current production lacks the dual input of it's earlier design. I think Channel Master should have changed the model number given such a drastic design change but that's just my opinion. Regardless of which version of the CM-7777 you have access to, I believe it would be at risk of overload. Channel Master is clear in their documentation that the CM-7777 is a weak signal amplifier, your TVFR indicates a few signals that don't fall into the class of 'weak signals'.

As teleview has requested already, a link to your TVFR is more helpful because it has links to path profile and pending data.

Based on what you've provided thus far, I would opt for an Antennas Direct DB4e and an Antennacraft Y10713 combined with a standard UVSJ, then into an Antennas Direct CPA-19.
