Moxon antenna calculator.

John Portune, W6NBC, describes how to build a 10M Moxon antenna.So perhaps a review of the antenna can put a few things into the right perspective. The Moxon rectangle is a 2-element parasitical beam or unidirectional antenna about 70% the length of a full size 2-element Yagi of standard driver-reflector design. The rectangle, however, far exceeds other 2-element beams in front-to-back ratio, while almost ...In order to use our antenna calculator, you'll need to know the frequency on which you want your antenna to operate..

May 1, 2014 · A horizontial moxon would be quite low profile compared to a Vertical Loop/Delta antenna. I may be able to mount it as high as 20 feet AGL before visability becomes an issue, roughtly 1/2 a wavelength on 11 meters, but I said 17 feet as a more probably number, and the extra 3 feet probably will not gain much.

Stumbled across a good Moxon Antenna Calculator this morning which was created by Paul Evans W4/VP9KF. Check the calculator and his site out here: http://w4.vp9kf.com ...

According to Moxon [], because of the very high impedance (i.e., very low current) at the end of a half wavelength antenna, only a small counterpoise (1m @ 14 MHz) or a few pF of capacitance to ground is required to return the current.However, in order to maintain a balance an equal amount of length is required to be added to the antenna itself. So even …Cut two pieces of wire 53 1/2 inches long (add an extra 1/2 inch or so for connecting the wire to the UHF connector) and one piece of wire 114 inches long.

Further Notes on 40-Meter Wire Moxon Rectangles L. B. Cebik, W4RNL. The growing interest in the Moxon Rectangle as a wire beam for 40-meter use has prompted me to collect some of my casual notes on the subject and place them here. The aim is to provide a few extra ideas for those wishing to experiment with the antenna.L. A. Moxon, in his HF Antennas for All Locations, provides the essential clue: "the main benefit [of a beam] accrues from the reduction of interference during reception, though the 4 to 6 dB gain provided by typical amateur beams is an important bonus and probably the reason which carries the most weight with the majority of amateurs."
