I recommend a Antenna Craft U8000 antenna aimed at about 257 degrees magnetic compass. The stations in the opposite direction 58 degrees are Very Strong and will be received through the back side of the U8000. No rotor will be needed and multipul antennas will not be needed. And No antenna amplifier will be needed for one Tv hookup. Here is how to aim antennas ,
