While the book covers a vast range of antennas—including wire dipoles, loops, and beams—it is most famous for popularizing the Moxon Rectangle , a design evolved from the VK2ABQ square.

A two-element parasitic beam with folded element ends that point toward each other. Performance: hf antennas for all locations moxon pdf hot

Known for an exceptionally high front-to-back ratio (often exceeding 30dB) and a compact footprint (roughly 70% the size of a standard 2-element Yagi). Construction:

Can be built from wire for portable use or aluminum tubing for permanent installations. It typically has a 50-ohm impedance, requiring no complex matching networks. A Design Study of Printed Moxon Antenna

3. Deployment for “All Locations”

  • Apartment/balcony: Vertical Moxon (elements on fiberglass poles). Aim through a window.
  • Small city lot: Inverted V Moxon — center up 25–30 ft, ends low.
  • Portable/POTA: Wire Moxon on two 10–12 ft masts. Folds into a backpack.
  • Stealth: Dark insulated wire, flat against roof or fence. Front/back ratio hides it.

2. Portable / Field Operations

Moxon antennas are popular for SOTA (Summits on the Air) and POTA (Parks on the Air). Made from fiberglass poles and wire, a 20m Moxon weighs under 1 kg and packs into a small bag. Setup takes 10 minutes. known as the Moxon Rectangle

The "Hot" Moxon PDF: Exact Dimensions for Key HF Bands

The following data is derived from the most frequently downloaded Moxon design tables. These dimensions are for wire antennas (using 14 AWG copper) or aluminum tubing. For a free-space Moxon (center-fed with 50-ohm coax), use these numbers.

Critical Formula (for mental math):

  • Driven element length (D1 + D2) = 588 / Frequency (MHz) in feet.
  • Reflector length (R1 + R2) = 612 / Frequency (MHz) in feet.
  • Element spacing (S) = 59 / Frequency (MHz) in feet.

1. Introduction

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."

6. Conclusion

The Moxon Rectangle stands as a testament to innovative antenna design. It disproves the axiom that effective HF antennas require vast acreage. By combining the mechanical efficiency of a shortened wingspan with the electrical efficiency of a directional array, the Moxon provides a "hot" solution for the modern amateur.

Whether constructed as a permanent wire fixture between trees or as a rotatable aluminum array, the Moxon is arguably the best "first antenna" for the aspiring DXer with a small lot. Its high front-to-back ratio, modest footprint, and excellent gain ensure that it remains a relevant and powerful tool in the HF arsenal.
