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.
http://www.instructables.com/id/Computer-controlled-OTA-TV-antenna/ - still in progress..
Step 1: Improvement over an existing form.
Update: apparently the web site with original instructions is no longer available. I will update this instructable with all the details soon. For the mean time I have some quickie drawings. I think the long sections might have been 14 - 17 inches long. I will have to remeasure everything.
