I want to cut the cord as well and I tried last year. My big problem then was that I was trying to use my PC as a DVR, and I just couldn't get Windows Media Center to play nicely (i.e. wake up for a recording, update the guide etc.) I am not tech dumb, but I'm definitely not savvy enough or have enough time to constantly fiddle with something like that. So, I am now thinking about buying an OTA DVR (Tivo Roamio or Tablo) but could use some advice on antennas myself.
During my attempt last year I used a passive indoor MOHU Leaf. It worked great for all stations except one. FOX would come in, but at times it would drop the signal or introduce weird green artifacts. That's bad, because FOX is the one station I really want to come in well (NFL games). According to TV Fool, all of the broadcast stations are about 4 miles North East of me. The TV and Antenna areon the second floor of my house. There is a HUGE tree outside in that direction so that could be causing some of the problem. Any ideas for an easy to install (I really don't want to put one on the roof) antenna that may work better?
