Welcome, Kentuckian:
I favor a more simple approach. Mount an Antennas Direct C2 aimed at about 105 to 110 degrees magnetic and be happy with the locals. No rotator needed, because the C2 has a wide beamwidth.
For your distant channels you would need a VHF/UHF combo antenna like the Winegard HD7698P and a rotator which would give you most of the same networks as a simple system. You would probably need a preamp which would be overloaded by your very strong local channels.
If the antenna is outside, 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 which will tend to discourage a strike, but the system will not survive a direct strike.
