The hot PDFs also include a "hairpin match" (a shorted stub across the feedpoint) to bring the impedance to exactly 50 ohms. On 20m, this is typically a 6-inch loop of 300-ohm twinlead or a 4-inch piece of wire folded back.
The Moxon is a two-element parasitic array (one driven element, one reflector) folded into a rectangular shape. Despite having only two elements, it achieves: hf antennas for all locations moxon pdf hot
That 4-6 dB reduction in receive noise is effectively the same as adding a pre-amplifier to your signal. That is what hams mean when they say a Moxon is "hot." The hot PDFs also include a "hairpin match"
Les Moxon, a renowned British engineer and amateur radio operator, developed the Moxon antenna in the 1950s. The design was initially intended for use on the lower HF bands, but its popularity soon spread, and it became a staple for many amateur radio operators. Despite having only two elements, it achieves: That
They built the frame in under an hour. It was a rectangle of wire, bent at the ends, looking deceptively simple. While the tower crew was still shouting instructions and tightening guy wires, Jerry and Alex carried the lightweight frame to a modest push-up pole.
Reducing the size of beam antennas without significant loss in performance.
