I tried the same Antop antenna you have up in the mtns..it's really poor in that environment..while I'm at 3700', even with the amp the signals are too weak due to distance for it. The 1byOne OUS00-0555 85 mile antenna out performs it at that location.
Of course, on one end of the house I get a different set of channels than the other end, so a bit of moving around is in order.
