Super antenna cheap.

One of my side hobbies is to make foil based equivalents of traditional antennas. This is my latest prototype of the Gray-Hoverman antenna. Just $5 dollars in materials. It is also almost light as a feather.

My next goal is to step it up a bit with commercial antenna clone. Probably do this one with coat hangers. Looking for the specs.
