Query: Works Flawlessly in Glenview, IL

I installed this antenna indoors on the second floor of my house, and I get all the major stations - 2 (CBS), 5 (NBC), 7 (ABC), 9 (WGN), 11 (PBS), 20, 23, 26, 38, 50, and a few other channels that I don't watch. Reception is crystal clear using both a Samsung 50" plasma and a Sony 55" LCD.I was concerned that CBS wouldn't come in because it's a VHF frequency broadcast instead of UHF, but the signal is strong, and watching March Madness basketball has been great.
