Hf Antennas For All Locations Moxon Pdf Hot Access

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

Among the various directional designs available to amateur radio operators, the stands out as a premier choice. This comprehensive guide explores why the Moxon is considered the ultimate HF antenna for virtually any location, how to optimize its design, and where to find the best PDF building resources.

Cut one length for the Reflector and one length for the Driven Element according to your calculator results. Mark the exact points where the wires will bend around the corners of the fiberglass frame.

Use the (a free executable program by AC6LA) or online modeling tools based on EZNEC.

Raise the antenna at least 10–15 feet off the ground during testing to minimize ground interaction. hf antennas for all locations moxon pdf hot

The reflector is usually 5-7% longer than the driven element. Never change them by different ratios.

The classic Moxon rectangle consists of a driven element and a reflector. The critical innovation lies in bending the tips of both elements toward each other. This geometry creates intense capacitive loading between the ends of the elements.

For hams with modest yards, a multiband Moxon nested array provides a highly effective directional system. By nesting smaller rectangles inside larger ones (e.g., 10m inside 15m inside 20m), operators can build a highly capable tri-band beam that takes up a fraction of the space of a traditional tri-bander Yagi. Sourcing Blueprints: The Quest for PDFs and Design Tools The Moxon antenna, originally detailed by Les Moxon

Conceived by the late Les Moxon (G6XN), the Moxon antenna is a two-element parasitic array that, on the surface, resembles a Yagi-Uda but with a clever twist. The driven element and reflector are folded inward at their ends, forming a rectangular loop. This folding isn't just for aesthetics; it serves two critical functions.

Bolt your four spreaders to the center hub in an "X" configuration.

The Ultimate Guide to HF Moxon Antennas: High-Performance Solutions for All Locations

Because the dimensions are critical but the structure is simple, a Moxon can be built using flexible wire and lightweight fiberglass crappie poles or spreaders. You can roll up a multi-band wire Moxon, pack it into a backpack, and deploy it on a lightweight mast in under ten minutes during a Parks on the Air (POTA) activation. Permanent Base Stations This comprehensive guide explores why the Moxon is

: 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.

Vertical polarization provides a much lower angle of radiation when mounted close to the ground.

The Moxon rectangle remains one of the most efficient, forgiving, and high-performing directional antennas available to the modern amateur radio operator. Its ability to pack excellent forward gain, massive noise rejection, and a native 50-ohm match into a compact layout makes it uniquely qualified for all locations—from pristine mountain peaks to cramped, stealthy suburban backyards.

The Moxon rectangle antenna solves this problem entirely. Originally designed by Les Moxon (G6XN), this modified two-element Yagi uses folded elements to reduce the antenna's physical width by approximately 30% without sacrificing performance. This article provides a comprehensive technical overview of the Moxon HF antenna, its deployment across diverse locations, and how to access essential design blueprints and PDFs to build your own high-efficiency station. Understanding the Moxon Architecture: Compact Power

Bending the elements reduces the physical footprint to roughly 70% of a standard two-element Yagi antenna.
