Hf Antennas For All Locations Moxon Pdf Hot
In the world of HF amateur radio, the eternal struggle is real: performance vs. space. You want the gain of a 3-element Yagi and the low-angle radiation of a dipole at 50 feet, but you live on a postage-stamp lot in an HOA-controlled neighborhood. Or perhaps you are a portable operator (POTA/SOTA) needing maximum punch from a minimal setup.
If you have searched for "HF antennas for all locations Moxon PDF hot," 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.
This article is your complete guide to understanding, building, and deploying the Moxon antenna—whether you operate from a downtown apartment, a suburban backyard, or a mountaintop.
The "ideal" HF antenna has traditionally been viewed as a full-size half-wave dipole or a monoband Yagi. However, these antennas present a logistical challenge for operators living on small lots, in apartments, or in communities with strict Homeowners Association (HOA) covenants.
Les Moxon (G6XN) popularized a design originally theorized by Albert Stegen, which challenged the notion that performance must be sacrificed for size. The resulting antenna, known as the Moxon Rectangle, offers a unique blend of compact geometry, gain, and a broadband match, making it one of the most effective antennas for "all locations."
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
The antenna consists of two rectangular "C" shapes facing each other:

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: hf antennas for all locations moxon pdf hot
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
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.

In the world of amateur radio and shortwave communications, the Moxon antenna has gained a reputation for being a simple, yet effective solution for HF (High Frequency) communications. Named after its inventor, Les Moxon (G3XN), this antenna design has been widely used by radio enthusiasts for decades.
A Brief History
Les Moxon, a renowned British engineer and amateur radio operator, developed the Moxon antenna in the 1950s. The design was initially intended for use on the lower HF bands, but its popularity soon spread, and it became a staple for many amateur radio operators.
Design and Characteristics
The Moxon antenna is a type of directional antenna, consisting of two parallel elements, typically made of wire or tubing, which are connected at their ends to form a rectangular shape. The antenna is usually mounted horizontally, with the elements parallel to the ground. This design provides a directional radiation pattern, with a gain of around 3-4 dB over a dipole antenna.
Advantages and Applications
The Moxon antenna offers several advantages that make it a popular choice:

The DX Secret Hiding in Plain Sight: Why Every Ham Needs a Moxon
If you’ve been chasing DX on a standard wire dipole, you’ve likely felt the frustration of being "heard" by everyone but "heard clearly" by no one. While a massive Yagi is the dream, most of us don’t have the acreage or the HOA’s permission for a 40-foot tower.
Enter the Moxon Rectangle—the "all locations" hero of the antenna world. What Makes the Moxon Different?
Named after Les Moxon, G6XN, this antenna is essentially a two-element Yagi with a twist—literally. By folding the ends of the driven element and the reflector toward each other, you achieve several massive benefits:
30% Smaller Footprint: A 10m Moxon is roughly one-third smaller than a full-sized dipole, making it perfect for balconies or small backyards.
Massive Front-to-Back (F/B) Ratio: While a simple Yagi might give you 10-15 dB, a well-tuned Moxon can push 25-30 dB F/B, effectively "silencing" interference from behind you.
Direct 50-Ohm Feed: No tuners or complex matching networks are required. You can plug your 50-ohm coax directly into the feed point. Build or Buy? (The "Hot" 2025 Trend)
In 2025, the "hammade" movement is peaking. Rather than buying bulky commercial beams, operators are using 3D-printed hubs and fiberglass spreaders (like crappie poles) to build ultralight, portable Moxons for SOTA and POTA.

In the late 1970s, a retired British radar engineer named Les Moxon (G6XN)
sat in his workshop with a radical idea: a beam antenna that didn't require a massive tower or a massive backyard . He eventually shared these secrets in his legendary book, HF Antennas for All Locations , published by the Radio Society of Great Britain The Secret of the Rectangle
While others were building standard square antennas like the , Moxon discovered that by stretching the shape into a
and precisely tuning the spacing between the tips of the wires, he could achieve a nearly perfect cardioid radiation pattern. This "Moxon Rectangle" provided: High Directivity
: Great "front-to-back" ratios that silenced interference from the rear. Compact Footprint : A wingspan roughly 30% smaller
than a traditional 2-element Yagi, making it ideal for restricted urban lots. Forgiving Nature : It could be built from simple copper wire and fiberglass spreaders , fitting where others couldn't. A Handbook for the Rest of Us
Moxon’s book became a "hot" item in the radio community because it focused on practical solutions
for difficult locations—urban rooftops, small gardens, and portable field sites. He famously avoided "brain-exploding" math, preferring sketches and real-world experiments that allowed amateur operators to build effective dipoles, loops, and beams on a budget.
