Happy Thanksgiving, treefrog

The antenna for your weak signals will be very large, and is determined by the real channels you want.

VHF-Low, real channels 2-6
VHF-High, real channels 7-13
UHF, real channels 14-51

If you want these real channels, it will need to be an all channel antenna like a Winegard HD8200P:
3 WJLP Me-TV
4 WPXO MundoMax
6 WRGB CBS
2 WKOB IQRA TV

If you can do without them, you can use a VHF-High/UHF combo antenna like the Winegard HD7698P.

It's a hard choice, because CBS with a good signal is rare on your report.

The Channel Master CM9521A TV Antenna Rotator seems to be popular, but I don't have any personal experience with it. If you want a heavy duty rotator that lasts longer, you will need to upgrade to a ham radio rotator, which is more expensive.

There is one strong local FM signal, but the FM filter in your preamp should take care of it:

WZME has a signal power of -65.5 dBm.

The max inpui of the CM7777 preamp is 15 dBmV = -34 dBm

The 7777 is easily overloaded.

-65.5 dBm + antenna gain 12 dB = -53.5 dBm, OK

-53.5 dBm + 30 dB preamp gain = -23.5 dBm which is below tuner overload, OK
