Hf Antennas For All Locations Moxon Pdf May 2026

The classic book HF Antennas for All Locations by Les Moxon (G6XN) is a seminal work for amateur radio enthusiasts, particularly those facing space constraints or difficult environments. Moxon is widely recognized for his expertise in designing effective antennas that prioritize performance even in restricted locations. 0x9900.com Moxon Rectangle Antenna

• A Moxon for a given HF band uses two rectangular elements with a calculated spacing and foldback (the exact dimensions depend on frequency). Typically built from insulated wire or aluminum tubing on a small boom.
• Feed the driven element center with a short matching section—commonly a 1:1 current balun—to feed coax.
• Tune lengths for resonance and adjust separation for best front-to-back and SWR.
• For multiband use, consider stacked or trapped Moxons, or deploy separate lightweight elements for each desired band.

High Front-to-Back Ratio: It is highly effective at nulling out interference from behind the antenna. hf antennas for all locations moxon pdf

The direct answer: No single Moxon can cover 80m through 10m due to the physics of element lengths. However, a fanned Moxon or switchable Moxon array comes close. The classic book HF Antennas for All Locations

Part 2: What is a Moxon Rectangle? (And Why the Hype?)

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. A Moxon for a given HF band uses

Direct Feed: It typically presents a near-perfect 50-ohm impedance, allowing it to be fed directly with coaxial cable without complex matching networks like baluns or gamma matches.

The antenna's legacy is rooted in Les Moxon’s seminal book, " HF Antennas for All Locations
