The top antenna is a 6 meter Yagi on a 12 foot boom. Below that is a 2 meter quagi on a 14 foot boom
and the bottom antenna is the W5UN 2 meter Quagi scaled to 70 centimeters using W7EL's EZNEC, fits on an 8
foot boom! The antennas are mounted on a 40 foot Aluminum pole with a rotator at its base and a support
bushing fastened to a roof beam of the carport. The mast mounted preamps are Icoms. It took a lot of
experimenting with EZNEC to find a stacking arrangement for these antennas that would result in clean,
undistorted patterns. For the 2 meter and 70 centimeter antennas it proved very worthwhile to adjust
their height so that they are near the 3, 9 or 15 wavelength elevations. In this case that meant that
the 2 meter beam is near 3 wavelengths above ground and the 70 centimeter beam is near 9 wavelengths
above ground. 6 and 12 wavelengths above ground are "dead" spots where the antennas performance really
fell off.
