I get a bar or two when I am on the first floor, but the basement is the killer. In the tv room I have a small window, but doesnt seem to help. Which 800mhz antenna would work the best? I checked scannermaster.com for the 800mhz antennas and they had about a half dozen different ones. Are they all about the same or any significant dfferences. Sorry for the elementary questions, thanks alot for your help.
