MOXGEN: A stand-alone Windows program that calculates the dimensions of a Moxon rectangle for a near-50-Ohm feedpoint impedance, as described in "Designing Moxon Rectangles by Equation and by Model," has been developed by Dan Maguire, AC6LA.
Invented by Les Moxon, G6XN, the MOXON is a stealthy gain antenna that's inexpensive and fun to build. It's a great Saturday antenna project especially for new hams seeking their first gain antenna. This antenna can be mounted on a simple push-up mast and rotated by hand or with an inexpensive light duty rotor.
Figure 1 compares the elevation plots of the two antennas and Figure 2 the azimuth. These plots were very encouraging. The Moxon should do much better, with a lower radiation angle and about 5.3 dB more gain, not to men-tion a front-to-back ratio of about 15 dB.
For 20 and 15 meters, a design frequency about 40% up from the bottom of the band provides whole band coverage. Therefore, 14.150 and 21.200 MHz are the design frequencies. On 10 meters, a frequency of 28.350 seems best for covering the entire first MHz of the band. The following chart provides the dimensions in feet. Moxon Rectangle Dimensions
Shown below are the dimensions for the 20 meter band.: Here we've started the moxgen software, used 14.175 as center frequency, selected our #12AWG wire and hit calculate. The results are shown in inches, but you could have selected other units.
2 dni temu · Review: Hi Paul I have used your Moxon calculator for 2 antennas. One for 24 MHz the other 18 MHz using Ali tubes. The calculator is spot on and no SWR adjustments required.
Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1] It takes its name from the amateur radio operator and antenna handbook author Les Moxon [2] (call sign G6XN). [1]
