Hf Antennas For All Locations Moxon Pdf -

The Moxon antenna, named after its inventor, Leslie Moxon (G3PPT), is a type of directional antenna that consists of two elements: a driven element and a reflector. The Moxon antenna is a compact, flat design that provides excellent performance and is relatively easy to build. Its unique configuration allows it to operate efficiently on multiple HF bands, making it a popular choice among amateur radio operators.

The natural resonant impedance matches native 50-ohm coaxial cables perfectly, eliminating the need for complex matching networks or lossy tuners.

, written by the legendary British amateur radio operator and wartime radar engineer Les Moxon (G6XN) , is widely considered a masterwork for solving these real-world antenna dilemmas. Published by the Radio Society of Great Britain (RSGB) , this book offers a deep, math-light understanding of how antennas interact with their surroundings. It serves as the foundation for the famous Moxon Rectangle antenna —a compact, 2-element directional beam that delivers outstanding performance in restricted spaces.

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. hf antennas for all locations moxon pdf

Programs like EZNEC or 4nec2 allow users to simulate a Moxon over specific ground conditions to optimize performance before cutting materials. Finding Comprehensive Guides and PDF Blueprints

When operating QRP (low power) from a park or mountain peak, every decibel counts. The forward gain of a Moxon ensures your 5-watt signal performs like a much stronger station, cutting through pile-ups far better than a standard vertical or dipole. 3. Maritime Mobile and Coastal Deployments

Developed by Les Moxon (G6XN), the Moxon antenna is a modified two-element parasitic array. It consists of a driven element and a reflector, characterized by rectangular shape and folded tips. The Moxon antenna, named after its inventor, Leslie

A Moxon antenna, also known as a Moxon rectangle or Moxon doublet, is a type of HF antenna that consists of two parallel dipoles connected at their ends. The antenna was invented by G3PAS (Les Moxon) in the 1950s and has since become a popular choice for HF communication. The Moxon antenna is known for its compact design, high gain, and directional radiation pattern.

You can find these downloadable reference manuals on major amateur radio archive sites like , eHam.net , or dedicated antenna design portals like Moxon Antenna Project archives. Simply search for "Moxon Antenna Project PDF" or "AC6LA Moxon Calculator" in your browser to access the printable schematics. 7. Conclusion

No towers, no visible large wires, “property aesthetics” clauses. The Moxon Solution: Build a stealth Moxon using dark enameled magnet wire (#14 or #12 AWG) framed by small diameter PVC or fiberglass poles. Mount it horizontally on a 20-foot telescoping flagpole or vertically against a wooden fence painted to match. The natural resonant impedance matches native 50-ohm coaxial

The folded ends introduce capacitive loading, which electrically lengthens the shortened elements. Furthermore, the close proximity of the element tips causes intense mutual coupling. This coupling optimizes the current distribution across both wires. The result is a highly focused forward radiation pattern and a deep null directly behind the antenna, allowing you to reject local noise and interference. 4. Design and Calculation Formulas
