VE3SQB ANTENNA DESIGN PROGRAMS EN82NE

FOR THE EXPERIMENTER

The second antenna is even simpler, consisting of only two bowed elements. While not as good as the first , it still shows promise and anybody could build it. Although originally designed for 137.5 wefax reception, circular polarized antennas can make nice standby omni antennas to monitor band openings, both horizontal base, vertical mobile communications or even for a beacon xmitter.

The omniquad (V2 corrected) is a very simple but excellent standby vertical antenna. I've built many over the years but just got around to making up a program. The main advantage is the extreme bandwidth. Make all the dimensional errors you want, and it will still work. You can use wire or tubing. A broom handle ,some 1/4 dowels and under 10 feet of wire will make a 2 meter antenna. There is very little gain or pattern difference between the 3 and 4 sided versions but the 4 sided version does give a better match. It can even be used as a desk top antenna.
