Hf Antennas For All Locations Moxon Pdf Hot 〈2K〉

Invented by Les Moxon (G6XN), the Moxon rectangle consists of two parallel elements: a driven element and a reflector, bent into a rectangular or "U" shape. The ends are folded inward, reducing the overall width by about 30–40% compared to a standard two-element Yagi.

Key characteristics:

The Moxon Rectangle is a two-element parasitic array (or a driven element with reflectors, depending on configuration) arranged in a rectangular shape. Unlike a standard dipole which is linear, the Moxon bends the ends of the driven element and the reflector inward toward each other.

This folding creates capacitive coupling at the ends of the elements. This coupling allows the antenna to achieve resonance in a significantly shorter physical length than a straight dipole. hf antennas for all locations moxon pdf hot

Les Moxon’s 1992 book (RSGB publication) is out of print. Clean PDF scans are highly sought after (and legally shared for personal use in many ham circles). Here is why the PDF remains the "hottest" download:

Warning: Do not just grab any random Moxon calculator online. Many web calculators use the wrong spacing formula. Stick to the original PDF data from G6XN.

| Band | Moxon Dimensions (approx.) | Best Use | |------|----------------------------|-----------| | 40m | 11 m wide × 5 m tall | NVIS + low-angle hybrid — requires tall supports | | 20m | 7.5 m wide × 3.5 m tall | Ideal all-rounder, fits in most yards | | 15m | 5.2 m wide × 2.4 m tall | Excellent for portable DX | | 10m | 3.8 m wide × 1.7 m tall | Small enough for a balcony or rotatable mount | Invented by Les Moxon (G6XN), the Moxon rectangle

Don't fear the tuning. Follow this routine from your downloaded PDF:

Warning: The reflector is usually 5-7% longer than the driven element. Never change them by different ratios.
