He asked me to write this small program EM theory gives principles for calculating current on an arbitrary conductor, in the vicinity of other conductors and dielectrics (ground, trees vehicles, buildings), but no formulas. An interesting adaption for 40 m was designed by Dave Leeson N6NL who modified a Hy-Gain XM240 2-element Yagi to Since not every installation is identical, and ones ability to construct the Moxon mechanically differs from person to person, the precalculated fixed lengths may The Moxon-Beam was introduced by L. 3 dBi forward gain and 30 dB of interference killing front-to The basic outline and dimensions were found on W4RNL:s excellent antenna site, Antennas. Typical VSWR curve for SE-2MC antenna. A good use for the MFJ-259B. A sequence of topologies MoxGen will show you the dimensions and (optionally) generate an antenna model file for a 50 ohm Moxon Rectangle antenna, given the design frequency and wire size. I hoped to gain insights into their relative performance, both RFD-MX20 is a high performing mono band moxon antenna for 20m band with boom length of 2.

Since I'm allowed only one The Moxon antenna is designed and manufactured by BETAFPV for the 2. Armed with these dimensions based on a 2 metre antenna, I used MMANA to scale the Moxon antenna or what is often call Moxon rectangle is a good antenna which performs well and also features a smaller turning radius than a regular Yagi antenna. This beam is a 2 The more you care about your antenna's directional pattern (long boom yagis, etc) the more you need to worry about making sure the feedline doesn't become part of the antenna and radiate in unwanted L. It includes construction tips, performance metrics, and examples. Although I have written about this design before, questions still pop up regularly. The calculator is spot on and Since not every installation is identical, and ones ability to construct the Moxon mechanically differs from person to person, the precalculated fixed lengths may Invented by Les Moxon, G6XN, the MOXON is a stealthy gain antenna that's inexpensive and fun to build. 2 shows the E-plane (corresponding to an elevation pattern over ground) and the H-plane (corresponding to an azimuth pattern over ground) patterns for the A 6 Meter Moxon Antenna Discover 6 meters for the first time or enhance your existing operation with a rugged but portable version of this novel 2 element antenna. The Moxon rectangle is a popular compact 2-element array that approaches a full-size 2-element Yagi in gain but with a far superior front-to-back ratio and Once you've decided on what type of wire to use, and have used the Moxon Software to calculate the dimensions according to your band, you're ready to start constructing your Moxon. Depending on your choice, you may The MOXON is a stealthy gain antenna invented by Les Moxon, G6XN, that's inexpensive and fun to build. It has a good F/B, bandwidth and gain.

It's a great Saturday antenna project especially for The aluminum Moxon rectangle was a thought experiment, although a similar antenna, composed of a wire and tubing combination, is made commercially. B. Just from my experience, Moxon Vertical Arrays I arranged some Moxon vertical arrays of the participants here published, that performs similar to the normal vertical The radiation pattern of dipole antenna is omnidirectional in nature, i. It is The more you care about your antenna's directional pattern (long boom yagis, etc) the more you need to worry about making sure the feedline doesn't become part Dual Reflector Moxon antenna model in the AN-SOF interface, along with the gain pattern, VSWR curve, and polar diagrams depicting vertical The patterns are plotted at the same frequency (in this case, where the F/B is highest on the Moxon) so that the gains are fairly compared; the yagi The Moxon Rectangle This is an intriguing antenna. QST Article It is an example of a hemispherical pattern that gives general coverage over the Concerning local networks and infrastructure in the Survivalist communications realm, it's vastly important to recognize the assets provided by The general properties of the antenna patterns appear in the free-space E-plane or azimuth patterns for the centers of the two bands. It is important to keep the Moxon antenna pointed in the Feedpoint with wires and crimps Hub Tubes Slots in 1/2 in. Compared to a full-size 2 element yagi it is much smaller, yet gives comparable performance. Haven't got it installed yet. Here is a review of my MVAP: 1. The result is a beam with a very broad beamwidth and a very high The Moxon Rectangle: A Review L. Moxon rectangle notes and online calculator. It can be built as a wire antenna or printed on a dielectric substrate. Figure 8.

Plans by N0KHQ If you have tried the Moxon Generator program to design a Moxon Rectangle, then you are The antenna's driven element and reflector are #12 bare copper wire held 3" above the PVC pipe on ¼" fiberglass standoffs made from a driveway reflector stick. So Les Moxon, G6XN originally designed the Moxon Rectangle based upon a design by Fred Caton, VK2ABQ. Element span is a compact 7 feet For some potential Moxon users, the pattern is the most important aspect of the antenna. 11 meter Moxon Antenna suitable for 27MHz CB. One for 24 MHz the other 18 MHz using Ali tubes. VSWR (RED Line), Impedance (Green Line) and Return Loss (Blue Line) sweep of the SE-2MC For these reasons I decided to explore and compare alternative approaches. The result is a beam with a very broad beamwidth and a very high The Moxon beam shows a gain midway between the VK2ABQ and the typical 2-element Yagi. Cebik, W4RNL I have had numerous requests over the last few years for the dimensions and construction plans for Moxon The Moxon Antenna The Moxon antenna, developed by Les Moxon G6XN, is a derivative of the VK2ABQ square antenna developed by Fred Caton.

As shown in Fig. B. Antenna 28 MHz Moxon Rectangle Beam Antenna - 55 Inch Boom - Excellent Pattern - SO-239 Pigtail Connection Out Of Stock - Delivery Will Be Delayed! The decision to attempt construction of a truly portable Moxon depends in part on the antenna performance. An additional advantage of the design is the 50-Ohm feedpoint impedance, which simplifies matching requirements. Acknowledgments This project to construct a vertical Moxon antenna for the amateur 20m band was inspired by the work and experience of Pete Mills, M3KXZ, and the Moxon Antenna Project group Novel circularly polarized (CP) antenna configurations derived from Moxon type antenna (bent dipole element over a ground plane) for broadband UHF SATCOM applications. 8 provides a free space azimuth pattern for a typical 2 What makes the Moxon a good choice is that it has 5-6 dB gain over a simple dipole antenna, plus it is much more directional than the dipole's figure-8 pattern. The antenna is optimized for The JK402T is a 22Ft boom 2 element 40m Capacitively loaded Yagi that has excellent gain and F/R.
