I'll never buy another Terk. It has become apparent that my 8-year old knows more about making antennas than they do. Their marketing department must be the same guys that pulled the MIT Blackjack scams!!!
personally I use the megawave amplified antenna. Only about $70 too at www.megawave.com. I tried a Terk antenna, and got 1 channel. Returned that one and got the megawave. Now I get every HD channel possible (around Boston) and only have to move it about 4 inches to get FoxHD.
Piss-poor luck on the $100 Terk HD99 or whatever it was. Couldn't get a thing... a piece of coax wired to my gutter did a better job than it. My $25 RS antenna works like a charm!
