To convince you that the Moxon truly belongs in every HF operator’s arsenal, here is a quick performance matrix (for a 20m antenna at 25 feet height):
| Antenna Type | Gain (dBi) | F/B Ratio | Width | Noise Immunity | | :--- | :--- | :--- | :--- | :--- | | 1/4λ Vertical | 0 | 0 dB | Very small | Poor (high noise) | | Half-Wave Dipole | 2.15 | 0 dB | 33 ft | Fair | | 2-Element Yagi | 6 | 15 dB | 18 ft (boom) | Good | | 3-Element Yagi | 7.5 | 20 dB | 24 ft (boom) | Excellent | | Moxon Rectangle | 5.5 | 28 dB | 13 ft (boom) | Excellent |
The Verdict: The Moxon yields 91% of a 2-element Yagi’s gain but with superior front-to-back in half the space. For crowded bands, the F/B ratio is more important than 1 dB of gain.
You have the theory, but you need the blueprint. A simple Google search often returns broken links or outdated calculations. Here is where to find legitimate, tested PDF resources:
Warning: 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. hf antennas for all locations moxon pdf
The reason so many operators search for a "hf antennas for all locations moxon pdf" is because of the "Multi-Moxon" concept. With a simple relay box at the center, you can change the feed point to operate on two different bands.
For example:
A better approach for "all locations" is to build a single-band Moxon for your favorite band (usually 20m, 17m, or 15m) and use a tuner for other bands. But the Moxon is so efficient that many operators build three separate small Moxons (10m, 15m, 20m) on a single cross-boom. This is a "Moxon array" and it fits in the same space as a single triband Yagi.
By James Miller, K6JM – Amateur Radio Enthusiast & Antenna Designer To convince you that the Moxon truly belongs
For decades, the dream of every amateur radio operator has been the same: to work the world on the HF bands from any location. Whether you live on a sprawling rural acreage, a suburban postage-stamp lot, or a high-rise apartment with a restrictive HOA, the laws of physics have always posed the same challenge—how do you fit a full-sized, high-gain, low-noise antenna into a tiny footprint?
Enter the unsung hero of compact directional antennas: the Moxon rectangle.
If you are searching for a single resource that combines theory, practical construction, and location-specific solutions, you’ve likely been looking for a comprehensive "HF Antennas for All Locations Moxon PDF" . In this article, we will explore why the Moxon design is the Swiss Army knife of HF antennas, how to adapt it to any QTH (from dense city centers to remote field operations), and where to find (or how to create) the definitive PDF guide that belongs in every shack.
Invented by Les Moxon, G6XN, the Moxon rectangle is a two-element driven and reflector array. Unlike a standard Yagi where the reflector is a single rod, the Moxon bends both the driven element and the reflector into a "U" or rectangular shape. Warning: Avoid PDFs that require you to pay $19
The Challenge: No towers, no visible large wires, “property aesthetics” clauses. The Moxon Solution: Build a stealth Moxon using dark enameled magnet wire (#14 or #12 AWG) framed by small diameter PVC or fiberglass poles. Mount it horizontally on a 20-foot telescoping flagpole or vertically against a wooden fence painted to match.
