Hf Antennas For All Locations Moxon Pdf -

While Moxon himself primarily wrote about the VK2ABQ antenna and wire-beam variations, his refinements led to what we now call the "Moxon Rectangle"—a two-element parasitic array with ends folded toward each other. Technical Breakthroughs

The Moxon is a balanced antenna. If you feed it directly with 50-ohm coax and the antenna is perfectly symmetrical, you may get away without a balun. However, for all locations except perfectly free-space, use a at the feedpoint to prevent the coax from becoming part of the antenna. A stack of 31 ferrite beads over RG-400 is your best friend.

It offers a wide main lobe (often over 100 degrees ), making it more forgiving to aim than a narrow-beam Yagi.

allows you to input your target HF frequency to generate exact wire lengths and spacing. Barrett Communications Why Choose a Moxon for "All Locations"? Compact Footprint

That evening, a rare 10-meter opening to Japan appeared. Leo’s usual antenna would have heard static.

Four fiberglass telescoping poles or heavy-walled UV-resistant PVC conduits.

The overall physical width of the front element.

Cut two rigid plastic or PVC strips to act as the gap insulators (Dimension D). Securely anchor the ends of the driven element and the reflector to these strips, maintaining the exact gap distance. While Moxon himself primarily wrote about the VK2ABQ

If you want the actual PDF: Search for “Moxon Rectangle Project” by L. B. Cebik (W4RNL) or use the free “MoxonGen” software. Most ham radio sites host the original 2-page build guide.

Mount your spreaders to the center hub to form an "X" shape or an "H" frame that matches the calculated rectangular layout.

Secure the driven element wire and reflector wire to the ends of the fiberglass spreaders. Use your non-conductive insulator to lock in the exact distance for Dimension C .

What if you could have a true bidirectional or directional antenna that is smaller than a Yagi, quieter than a vertical, and buildable from scrap wire in an afternoon? However, for all locations except perfectly free-space, use

The genius of the Moxon design is its versatility, proving effective in a wide range of operating environments:

HF Antennas for All Locations: The Moxon Design High-frequency (HF) radio operators often face a difficult choice. They must choose between large, high-performance directional antennas and smaller, less efficient omnidirectional wires. The Moxon rectangle offers an elegant solution to this problem. Invented by Les Moxon (G6XN), this design provides directional gain in a remarkably compact footprint. It is an ideal choice for hams with limited space, strict homeowner association (HOA) rules, or portable operating needs.

A 1/4-inch thick aluminum or heavy-duty UV-rated plastic plate (approx. 8x8 inches).

Utilizing 3D-printed center hubs and telescoping fiberglass poles allows the entire antenna to collapse into a backpack-friendly bundle.
