When I read your description I thought I was going to see many strong signals in the same direction. But, the report doesn't seem to match your description. I don't see transmitters 8 miles away and the location seems to be closer to Chestatee than Dawsonville.

Assuming the report is correct,
WXIA NBC, real channel 10, virtual 11.1, NM 16.3 dB, 210 degrees magnetic
WAGA Fox, real channel 27, virtual channel 5.1, NM 12.3 dB, 212 degrees magnetic
WGCL CBS, real channel 19, virtual channel 46.1, NM 14.0 dB, 212 degrees magnetic

WSB ABC on real channel 39, virtual channel 2.1, might also be possible, but it is a little weaker.

Those signals are listed as 2Edge which makes them less reliable because of terrain obstructions. I would like to give a guarantee for the young couple, but hesitate to do it because of so many unknown factors. See example in attachment 1.

They will need a high gain VHF/UHF combo antenna with a preamp mounted outside aimed at 212 degrees magnetic. The antennas to consider are the Winegard HD7697P and 7698.

The preamps to consider are the Channel Master 7778 and RCA TVPRAMP1R. The RCA is less expensive but might be less reliable.

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. See attachment 2.
