Thanks to YouTube, I put together this simple HDTV antenna last night to be able to watch football games while camping. It's made with clothes hangers, and I'm absolutely astounded on how well it works. All our TV transmitters are about 50 miles away, and we're able to catch 18 - 20 HD channels crystal clear. The total cost was about $6 ($4 for the transformer and $2 for the board). Most people have wire coat hangers hanging around and probably even a board and transformer from the good ole days so it can be built for free. I'll probably paint the board gray and also need to rig up a pole to use it on the PUP.
