I stumbled across this site -
http://www.hdtvprimer.com/ANTENNAS/comparing.html and am leaning towards the Winegard PR-4400 or 8800, since those Antennas have at least SOME response in the high VHF range - channels 7 and 9 are strong enough that I get them very clearly with rabbit ears, so hopefully I'll be able to get them with the 8800.
