I've got a MyHD MDP-130 and a Zenith Silver Sensor, and I'm about 30 miles from the transmitters. The only channels I can get on a consistent basis are NBC, CBS, and PBS. The NBC and CBS stations are based in Cincinnati, and I'd really like to get ABC for the Super Bowl. ABC transmits with a VHF signal, and the Silver Sensor only does UHF (although apparently all UHF antennas are capable of doing hi-VHF). I've tried a couple indoor VHF/UHF antennas with no success (RCA ANT145 and Radio Shack 15-1892). Are outdoor antennas able to receive signals better because of the size and complexity, and being placed outdoors is mainly for convenience's sake? I've got enough room indoors to place the outdoor antenna in. I don't want to put it on the roof (I've in a rented townhouse, there's no way I'm going up there to install it myself [if my contract with my landlord even allows me to] and I'm only here for a few more months, so hiring someone to install it on the roof isn't worth it for me). Will the signal be significantly weaker if I put it indoors instead of outdoors? I get NBC at 40-60%, CBS at 30-50%, and PBS at 40-50% with the Silver Sensor. My zip code is 45056.
