Getting away from the very boring rules and regs, here is a site for you
advanced antenna builders. Have fun watching it.
Here's a very nice short video showing how the reflector and director
elements of a Yagi antenna focus radio signals. The demonstration by Diane
Eng (KC2UHB, I believe) uses a light bulb and handheld dipole as the
receiver. This may be just the thing for teaching a new ham about Yagi
antennas. There are complete construction directions on the Web page, as
well, and several links to other ham radio videos. The Yagi used for the
demonstration is a dual-band "Cheap Yagi" design from WA5VJB. (Thanks, Paul
