Advertisements Concur also. Approximately 65-miles is the digital cliff, meaning the signal is being lost at that point via the curvature of the earth. Amplifying the signal will do nothing to help the situation as it will amplify the noise that harms the signal also. My experience in "deep fringe" areas like this (my grandparents lake house is 55mi from towers over rolling, tree filled terrain) is to get a high gain antenna, mount it as high as possible, make the coax run as short as possible to the tuner. Personally, I've had zero luck with pre-amps, they have only made things worse in my practice. Amplifying a signal that doesn't exist, amplifies nothing.
