I have one of those little (8x10) flat ones , I traded a guy in a Toyhome I met in a Wally's pkg lot even for some old rabbit ears I had kicking around. (he couldn't get it to work ,,, turns out he had the wires reversed on the booster amp !) I saw something similar at Wallys for $60.
I'm using it now as I type this ,getting 18 channels over the air some are HD! .
I'm about 25 miles from the nearest city.
