HF Antennas for All Locations : L. A. Moxon - Internet Archive
You can find several Moxon antenna build guides online that use everything from copper wire and PVC to fiberglass fishing poles. However, if you prefer a ready-to-install solution, there are excellent commercial options available.
If you have tried dipoles (boring), verticals (noisy), or compromised loops (inefficient), you are ready for the Moxon rectangle. It is the ultimate because it scales from a 160m behemoth down to a 6m pocket rocket.
Because the Moxon can be built as a small magnetic loop variant (though less common) or a wire version strung between trees, it offers directivity without a large rotator. Some amateurs hide Moxons in attics or along fences.
It consists of a driven element and a reflector, but they are bent back towards each other, forming a rectangular loop. This folding creates superior capacitive coupling.
If you have searched for you have stumbled upon the single most effective solution for confined spaces. The Moxon rectangle is not a compromise antenna; it is a directive antenna that defies its small size. And the reason the "PDF" is "hot" is simple: the original design summaries by Les Moxon, G6XN, are gold-standard engineering, easily downloaded, printed, and built in a single afternoon.
