Optimized 144MHz Moxon Antenna
The OM-144 is a horizontally polarized, directional antenna designed for the CW/SSB portion of 2M. The Moxon design occupies approximately ½ the real estate of a classic 2M Yagi style antenna (29" X 13"). The closed rectanglular design is mechanically very strong and rigid once assembled. Wind loading is a mere 21 square inches (0.14 square feet) and at 1 pound would would be virtually invisible to wind and snow loading.
When optimized and used with an effective balun (included in our matchbox), the Moxon design presents a very clean pattern devoid of the multiple sidelobes present in Yagi designs.
