As tigerbangs said, it is not really possible to predict how well an indoor antenna will perform. Too many variables involved. Therefore, with indoor antennas you don't base your decision on the antennaweb or tvfool information - you simply choose the "best" one and that's it.
I would suggest
Winegard SS-3000 or
AntennasDirect DB2, and I make this recommendation without even looking at your zip code.
