Moxon antenna calculator

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. The program is based on an algorithm developed by L. B. Cebik, W4RNL. For an overview of this antenna see the Cebik article The Moxon Rectangle: A Review .

For most VHF uses, it is the pattern shape, with its very high front-to-rear ratio, that holds more interest than the antenna's gain. Fig. A shows the azimuth pattern of a 2-meter Moxon when the antenna is vertically oriented and, hence, vertically polarized. Patterns are shown across the 2-meter band for a model designed for 146 MHz. 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 equalling them in gain. This combination of properties is prized by those who adhere ...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.

Paul takes you step by step through the design, construction, testing, and on-air …A Hybrid Tri-Band Moxon-Yagi. One of the features of the Moxon rectangle that appeals to many builders is the reduction in side-to-side width of the antenna relative to linear elements. On 20 meters, the normal 36' elements are reduced to 25' side-to-side--a value not much greater than the width of a 15-meter beam. Even if you don’t have a physical calculator at home, there are plenty of resources available online. Here are some of the best online calculators available for a variety of uses, whether it be for math class or business.
