Moxon Rectangles

### L. B. Cebik, W4RNL (SK)

The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a
full-size 2-element Yagi in gain but with a far superior front-to-back ratio and a direct match for
the standard 50-Ohm coaxial cable. The antenna can be built as a wire array--especially for
the lower HF regions--or as a rotatable aluminum beam. For convenience, I have
pulled together the growing selection of Moxon Rectangle notes into this single
subdirectory and organized them in the order of recommended reading.

Additional information on building wire and tubing versions of Moxon rectangles for a direct
50-Ohm feed is available in **Simple and Fun Antennas for Hams**, ed. Hutchinson and Straw (ARRL, 2002),
pp. 12-19 to 12-28. The **KD6WD Moxon Antenna
Project** at Murray State University is another good source of information on various construction
techniques, especially for the operator needing a light-weight or a semi-stealthy antenna.

Below is a version of the Moxon dimension calculator that you may use right on this page, thanks to
Joe Faber, KG4UHP, who created the JAVAScript and gave me permission to place it here. Remember that
the dimensions apply to Moxon rectangles that use the same diameter material throughout. Decide on the
design frequency and the diameter of the elements. You may use inches or millimeters for the
diameter--or you may select an AWG wire gauge. Be certain to select the unit of measure for the output.
Then, click on any of the output boxes if the calculations have not already appeared.
