The Magic Wand Antenna A Novel 2 Meter Full Wave Quad Loop By WB5ISM JERRY RANDALL (SK March 12, 2011 - See update below) DON'T LAUGH about this antenna! Ripley says "Believe it or Not"! The idea for this 2 meter full wave loop antenna came from QST., February, 1973. The design from QST was altered to eliminate instability in matching to a 50 ohm transmission line. The method used to obtain this new design was strictly through experimentation. Below is a trial by jury! We present the evidence! Description: The antenna is basically a quad, 1 full wavelength at 2 meters. Part of a wavelength on top and part on the bottom in the form of two loops connected together. The feed point is in the vertical plane of the antenna between the loops so it's basic polarization would be vertical. There are some horizontal characteristics common to all quad type antennas. This antenna is omni-directional but, it does have some directive characteristics. They ar
