TriQuest AMPLIFIED Indoor Antenna - $9.99 Big Lots B&M YMMV
At Big Lots, I picked up a TriQuest Amplified Indoor Antenna for 9.99. I have tried it out , and it works pretty well for me. Without much adjustment, I picked up a couple of channels from Winston-Salem/Greensboro, which is about 50 miles away, and I was able to pick up all of the Charlotte channels except 1 or 2. Performance might vary according to your location.
Reviews are kind of mixed, but leaning towards "good to try for ten bucks"
The only problem i have is that the coax cable is really short. I might actually pick up a couple more, and take apart 1 of them to look@ the amplifier section, maybe with a little patience and some soldering skill, I can make an in-line amplifier for $10, these normally sell for $35-$40
EDIT: Oops, the other antenna is from monoprice, not meritline
