Hf Antennas For All Locations Moxon Pdf [verified] May 2026
HF Antennas for All Locations by L.A. Moxon (1982) is a definitive guide on constructing high-performance, space-efficient antennas for amateur radio, particularly popularizing the 2-element "Moxon Rectangle" design. The book provides practical techniques for optimizing HF performance in limited spaces by focusing on antennas with high front-to-back ratios and direct 50-ohm feeds.

High-frequency (HF) antenna design often involves a trade-off between gain, size, and bandwidth. The Moxon Rectangle addresses these constraints by utilizing a "rectangle" of wire or tubing, where both the driven element and the reflector have ends folded toward each other. This configuration provides directional properties comparable to a two-element Yagi but in a significantly smaller physical area, making it ideal for "all locations," including space-restricted urban environments and portable field operations. 2.

Part 5: The "All Locations" Secret – The Adjustable Moxon
The reason so many operators search for a "hf antennas for all locations moxon pdf" is because of the "Multi-Moxon" concept. With a simple relay box at the center, you can change the feed point to operate on two different bands. HF Antennas for All Locations by L
- Printable 1:1 drilling templates for common tube sizes
- Wire layout jigs
- If dip is too high in frequency: The antenna is too short. Add wire length to the driven element ends (the "A" dimension).
- If dip is too low: The antenna is too long. Shorten the driven element.
- Compact design: Moxon antennas are relatively small, making them suitable for limited spaces, such as backyards, balconies, or even indoor installations.
- Easy to build: The design is simple, and the antenna can be constructed with minimal materials and expertise.
- Good gain and directivity: Moxon antennas have a moderate gain (around 6-9 dB) and a relatively broad beamwidth, making them suitable for DX (long-distance) communications.
