The Moxon Rectangle: Efficient HF Performance for Every Location
The Moxon antenna, originally detailed by Les Moxon (G6XN) in his seminal book HF Antennas for All Locations, remains a top choice for amateur radio operators facing space constraints or requiring portable setups. Often described as a "bent Yagi," this two-element beam provides a unique balance of directivity and compact footprint. Why the Moxon is "Hot" for HF
The Moxon’s popularity stems from its ability to outperform simple dipoles while being significantly smaller than traditional beams.
Compact Footprint: Folded ends reduce the overall width to approximately 70-75% of a full-size dipole or 2-element Yagi.
Terrific Front-to-Back (F/B) Ratio: It is famous for a deep rear null, often exceeding 30 dB, which "silences" interference from behind the antenna.
Direct 50-Ohm Feed: Unlike many beams, the Moxon typically presents a natural 50-ohm impedance, allowing you to connect coaxial cable directly without complex matching networks.
Broad Bandwidth: Its performance holds up well across an entire ham band, especially when constructed with thicker materials like aluminum tubing. Essential Design Principles

Unlocking HF Communications: A Guide to Moxon Antennas for Any Space
Finding the right antenna can be the biggest hurdle in amateur radio, especially when you are dealing with limited space or restrictive homeowner associations (HOAs). One of the most effective solutions is the Moxon Rectangle, a design popularized by Les Moxon, G6XN, in his seminal work, HF Antennas for All Locations .
Whether you're a seasoned DX hunter or a new ham looking for a weekend project, here is why the Moxon is considered a "hot" topic in HF antennas today. What Makes the Moxon Antenna Special?
The Moxon antenna is essentially a two-element Yagi with the ends of the elements folded toward each other. This design provides several distinct advantages:
Compact Footprint: Because the elements are folded, the antenna takes up roughly 30% less space than a full-size dipole.
Exceptional Front-to-Back Ratio: It is famous for its high front-to-back (F/B) ratio, often exceeding 30 dB. This allows you to "null out" interference from the rear while focusing on the station you want to hear.
Easy Matching: Most Moxon designs present a near-perfect 50-ohm load, meaning you typically don't need a lossy matching network or tuner.
Wide Bandwidth: The folded ends act as capacitive loads, which broadens the SWR curve and provides a larger usable frequency range than a standard dipole. Building vs. Buying
