a home made digital TV antenna

Had I not almost everything I needed laying about the tool shed, this antenna might have cost as much as $20 to make. A piece of 2x4. Some wire. A piece of PVC pipe. Some little lag bolts. I purchased a balun (a type of transformer) on Ebay for $3. You can by a similar device at Lowe's for about $4. I didn't know it at the time.

(Once the first layer of papercrete cures, the walls are firm enough to daub on more. The finished wall, with the faux stones attached, is several inches thick and seems to be very strong.) Anyway, I experimented by attaching some recycled aluminum window screen to the inside wall and coating it with the latex paint, sand and cement mixtu
