The design inherently offers a low Voltage Standing Wave Ratio (SWR) across the entire band. hf antennas for all locations moxon pdf
The magic of the Moxon is in the spacing. The tips of the elements should be kept apart by about 1-2% of the wavelength to prevent shorting.
For amateur radio operators, the quest for the perfect High Frequency (HF) antenna is often a battle against restricted space, homeowners' associations (HOAs), or the need for portability. While large Yagi beams offer superior gain, they are impractical for many. Enter the Moxon Rectangle
Early versions of the concept (known as the VK2ABQ square) had elements that were too close together. Moxon made two critical discoveries: the rectangular shape significantly improved gain, and the spacing between the bent ends of the wires was crucial. By increasing this spacing beyond what earlier designs used, Moxon unlocked the antenna's full potential. This spacing is carefully optimized to create the ideal current distribution on the reflector element, which is responsible for the antenna’s outstanding front-to-back (F/B) ratio—often exceeding 30 dB on the design frequency. A high F/B ratio means the antenna is extremely effective at rejecting signals coming from behind it, a highly desirable trait for reducing interference and improving weak signal reception. While an F/B ratio over 30 dB is possible, it is somewhat frequency-dependent, decreasing as you move away from the antenna's design frequency. The reference to HF Antennas for All Locations
When installing a Moxon antenna, consider the following factors to optimize its performance:
Because this book is older (1982), many radio enthusiasts look for it in digital format. Several public archives and digital libraries offer the HF Antennas for All Locations PDF, allowing users to study the designs in detail.
It typically maintains a low SWR across a broader range of frequencies than similar designs. Digital Access If you share with third parties, their policies apply

High-frequency (HF) antennas are a crucial component of any amateur radio or shortwave communication setup. With the increasing popularity of digital modes and global communication, having a reliable and efficient HF antenna system is essential. One popular design that has gained widespread acceptance is the Moxon antenna, named after its inventor, Les Moxon (G3PPT). This essay provides an in-depth look at HF antennas, specifically Moxon antennas, and their suitability for various locations.
