Wingard makes an 8200U that is cheaper than the 3671 Channel Master. The specs look pretty good on it. I put a signal amp on my 3671 (CM7777). I'm getting 30 channels at night and 20 during the day. Wingard also has a signal amp that is about 20 bucks cheaper with similar specs. I pointed my antenna at Savannah, GA and get Augusta, GA on the backside. That way I didn't need a rotor.
