2m Band Moxon - Moxon is a rectangle shaped directional antenna, originally designed by Les Moxon G6XN. There are couple of advantages of using this antenna. It is small in size, Easy to mast, Balanced to 50 Ohms, Near 1:1 SWR, Excellent Front to Back (F/B) ratio, Large bandwidth. understanding of the VK2ABQ/Moxon beam potential, and they form a basis for constructing some interesting real antennas for both limited space and portable operation. The VK2ABQ Square Moxon's search for a little gain and a lot of front-to-back ratio excludes the folded X-Beam from consideration here. Fig. 2 shows why. Although the front-to ...2m Band Moxon - Moxon is a rectangle shaped directional antenna, originally designed by Les Moxon G6XN. There are couple of advantages of using this antenna. It is small in size, Easy to mast, Balanced to 50 Ohms, Near 1:1 SWR, Excellent Front to Back (F/B) ratio, Large bandwidth. The telescoping feature is important. It helps in transportation and makes tuning the antenna a snap. The beam’s driven element should be 17.3 feet. The length of a reflector for a two-element Yagi with 0.116-wavelength element spacing should be 18 feet 1/2-inches.

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 ...Further Notes on 40-Meter Wire Moxon Rectangles L. B. Cebik, W4RNL. ... Almost any antenna design has a minimum diameter (and consequential surface area) for the efficiency to approach or surpass 99%. #14 wire is too small to achieve this figure in the Moxon rectangle, since the single wire model reports a 95.3% efficiency. ...Details. Compact 7-Element / 3-Band Beam with Moxon element for 10/15/20 m. The "3BMOX" is a compact yagi antenna with a moxon element as a radiator.

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 …

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.

This improvement will assist the outcome to be more efficient antenna with less losses regarding gain.
