6 METER MOXON ANTENNA

This is a 2-el Yagi made from dipoles bent in the shape of a U, the longer element is the reflector, the input Z is 50 ohms and no matching network is needed.



Gain is about 6 dB, FB about 25-30 dB.

Resonant Frequency = 51.088, SWR = 1:1 measured with MFJ 269 Analyzer.

SWR is under 1.6 from 50.000 to 54.000 MHz.

Driven Element is 80in end to end with 1/2in space at feed point. The driven element also has a 10 1/4in elbow on both ends.

Reflector Element is 80 1/2in end to end, with 15 3/8in elbow on each end.

Width of antenna is 29 3/4in. Spacing between Driven element and Reflector element elbows is 4 1/8in. Make the SWR measurements by moving the reflector close to the driven element or away from driven element.

This was a fun project, coming from a Lawn Chair to an Antenna that works great, it has been tested and works great. Refer to website www.moxonantennaproject.com/design.htm

2 METER MOXON ANTENNA

MOXON ANTENNA: Invented by Les Moxon G6XN (SK 2004), is sort of a two element yagi with the elements folded and spaced to eliminate the need for an impedance match.
A carefully optimized and constructed moxon can easily exceed the gain and bandwidth of a sloppily designed and constructed yagi. Also, the moxon is smaller than the typical yagi and much smaller than the typical J-pole antenna.
The Gain is typically 7-14 dBi, depending on accuracy of construction. Although this is a directional high gain antenna, it has a very large aperture with a high front to back ratio. If pointed directly up, this can make a decent satellite antenna.




Lawn Chair parts for the antenna.
Corners from lawn chair with wood separators, one screw is good to hold it together.
Almost an antenna.



Make both sides the same, connect the coax and have some fun




THIS ANTENNA WORKED BETTER THAN EXPECTED, Had fun making this antenna, the Moxon Calculator can be found on line, making measurements easy.
