My over the air dtv antenna. This is basically like the coat hanger antenna, but takes less space, safer if you have children around, and can be hidden behind a picture frame. I almost just poked my out with our coat hanger antenna. It was replaced with another foil dtv antenna. If you made one of those portable dtv converters, this will go perfect with it.
The video I watched to make my first OTA coathanger antenna and gave me the idea for the foil antenna:
Coming soon: Computer controlled OTA antenna. It's mostly done, Just have not made time to finish it.
