I favor the Channel Master 7777 for you. It is easily overloaded, but I don't see any very strong signals in your report that would do that.
I also did an FM signal report using your short coordinates. I don't see any FM signals strong enough to interfere with TV reception, and the 7777 has an FM filter.

The Kitztech and Research Comm preamps are in a special class with ultra low Noise Figures to receive weaker signals, but they are more sensitive to static damage; that's the trade-off. Both manufacturers have added protective devices to reduce possible static damage.
If you go with Kitztech, the reports say go with the 200 for a low NF. Calaveras at AVS has done extensive testing of preamps for NF and SFDR. Spurious Free Dynamic Range defines the ability to receive weak signals when you also have strong signals that might interfere.
