I don't want to get your hopes up or waste your money, but if you want to try with no guarantees:
in increasing magnitude order:
Winegard HD7694P
Winegard HD7694P + Channel Master 7778
Winegard HD7698P + Channel Master 7778
You have some strong local FM signals that might interfere with TV reception; use an FM trap. The 7778 has one built in. Without an amp insert an FM trap in the coax. See attachment.

The coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
Good Luck!
