The design parameters for a Moxon antenna are crucial to its performance. Here are some general guidelines:

The length of the wire folded toward the back.

A crucial feature is the small gap between the folded ends of the driven element and the reflector. hf antennas for all locations moxon pdf

The foundational resource for anyone serious about this antenna is L. B. Cebik's (W4RNL) . While not a PDF found online with a simple search, this 214-page book is widely considered the most complete and definitive study of the Moxon rectangle design ever published. It covers everything from basic principles to advanced optimization techniques and is an invaluable reference for experimenters.

Avoid PDFs that require you to pay $19.99 for "secret blueprints." The Moxon is open-source hardware. The math is public. Anyone selling a single PDF is likely just repackaging Les Moxon's 1982 RSGB article. The design parameters for a Moxon antenna are

Driven Element (Fed in center) ┌─────────── ───────────┐ │ │ │ [Space/Insulator] │ <-- Folded Ends │ │ └─────────────────────────┘ Reflector

The dimensions below are representative for a basic design, using common specifications for clarity. These are provided as a general guide; always use a specific calculator for your exact frequency, wire diameter, and materials. The foundational resource for anyone serious about this

For a successful "all location" install, ensure the antenna is mounted at least 1/2 wavelength high

The reason the keyword is so popular is simple: scarcity of space is the #1 problem for modern hams. The Moxon rectangle solves that problem with elegance.

Build the antenna 3-5% longer than calculated. You can always shorten wire. You cannot stretch it. The Moxon is sensitive to corner angles (90 degrees is ideal).
