"When I first got an HDTV I still had SD service from my satellite company and couldn't check out the HD quality. After searching the web a bit I came up with a few DIY HDTV antennas. The first one I built was a fractal antenna. It wasn't exactly to spec. I made the antenna out of some paperclips, staples, cardboard and a balun I had."
