A large antenna such as the Winegard HD7698P or Channel Master CM5020 pointed West toward Mt Wilson may give you some of the stations down in the red shaded section of your report. However, it looks doubtful that you would get reliable reception of all the major networks. There are other antenna options such as the Antennas Direct DB8E
combined with a Stellar Labs 30-2476 but these would not be a large step up in performance, they would offer the flexibility of independent aiming... which might prove somewhat helpful in your case.
The following link shows how the mountainous terrain blocks your view of the signal from Mt.Wilson.

The bottom line is that signals that are "Line of Sight" and listed in the green and yellow sections of your report will be the most likely 'reliable' signal for you. Signals that are "2-Edge" and listed in the red and grey sections of your report will be much more challenging to receive and if received, may be prone to drop outs.
