Hf Antennas For All Locations Moxon Pdf Direct
"Impossible," the voice replied. "You have no noise. You sound like a broadcast station."
An antenna design must adapt to its physical surroundings. The Moxon rectangle can be modified to suit various deployment constraints. 1. Urban and Space-Constrained Residential Environments
The table below shows complete dimensions for wire Moxons for popular HF bands, assuming 1-mm non-insulated copper wire and a 50-ohm feedpoint, which is a great starting point for your project.
The Moxon antenna has several advantages:
The Moxon antenna is a testament to how smart design can overcome physical constraints. More than just a hardware project, it represents the core of the amateur radio spirit: problem-solving, continuous learning, and building something with your own hands to connect with the world beyond your backyard. hf antennas for all locations moxon pdf
No holes in walls, no ground radials, high noise from switching power supplies. The Moxon Solution: Build a small magnetic loop? No – build a portable Moxon for 15m or 10m and mount it on a photography light stand inside a balcony or on a push-up mast clamped to a deck railing. Because the Moxon has deep nulls on the sides (off the tips of the rectangle), you can orient it to null out a noisy neighbor’s plasma TV or a specific apartment building’s switching supply.
Because the elements are folded, the overall turning radius is small. This allows operators to build a Moxon using lightweight fiberglass crappie poles or wire supported by a PVC frame.
This geometry introduces significant advantages over traditional antenna designs:
Always use a Moxon Calculator to determine the exact length of the driven element, reflector, and side length for your target frequency. Conclusion "Impossible," the voice replied

A square piece of heavy-duty plastic, cutting board, or aluminum plate with U-bolts.
Do you plan to build it from (portable) or aluminum (permanent)? The Moxon rectangle can be modified to suit
2 small PVC or plastic spacers (to maintain the precise gap "E"). 1 1:1 current balun or ferrite choke beads. 2. Calculate the Dimensions
For the next hour, Leo worked Japan, New Zealand, and Brazil. The PDF had promised a 20 dB front-to-back ratio—meaning he couldn't hear the neighbor's plasma TV or the HOA chairman's leaf blower behind him. It delivered.
Hence the phrase “for all locations” — from crowded urban homes to remote summits.
This article explores why Moxon antennas are perfect for all locations, how they work, and how to find comprehensive to build your own. What is a Moxon Antenna? Developed by Les Moxon (G6XN) in the 1950s, the Moxon Rectangle Go to product viewer dialog for this item.
