When I got my AM21N, I just connected a piece of coax cable to it, cut the end off and stripped the cable, and stuck it out the window. I was getting pretty good signal on the 2 main stations I want. Channel 8 was 7-85, and 6 (44) was 79-85, while 13 (38) was getting 61-64 (Don't really need this station, but if I get it, it's an added bonus). I figured I'd up the signal some, and increase stability with an antenna, so I got the Winegard FreeVision FV-HD30 http://www.solidsignal.com/pview.asp?p=FV-HD30&d=Winegard-FreeVision-FV-HD30-Compact-Ultra-Powerful-DTV-TV-Antenna-Free-Vision-%28FV-HD30-FV-30BB%29-. Just placed it outside, and connected it to the AM21N, and I'm actually getting LOWER signal than the plain coax cable! 8 and 6 (44) were in the low-mid 60's, and 13 (38) was in the low 50's! It was a temp mount, but I wasn't anywhere near the antenna while checking signals. Is coax really that good, or is the antenna just that bad?
