A few years ago I read an article online about making a cheap TV antenna. I had a TV in my shop and wanted to be able to watch TV. I didn't have much faith in it working. I just used stuff I had laying around in the shop. It worked and worked pretty good I was able to get 18 channels. I was watching HD TV in no time. The first one was pretty crude and far from pretty. I posted that little project on the sister site WFM. Over the years I heard from several guys that after they read that post they made there own...and they worked.
My son is working as an intern and didn't want to pay for cable. He's a big John Deere guy, so I made him an antenna and thought I'd pass the info on to anyone that might be interested. The new one gets 26 channels. Here's a link for one similar to mine. Watch Television For Free - DIY Digital TV Antenna Searching Google Images might be a better way to go. Don't get too hung up on making the dimensions exact, you only have to come close.
The first one in the shop. Look Emergency is on.
Proof it works!
