Hf Antennas For All Locations Moxon Pdf =link= [1000+ HOT]
Precise dimensions are critical to achieving the characteristic high front-to-back ratio of the Moxon. The antenna layout is divided into five critical dimensions:
The book is available in several formats for those seeking a "pdf" or digital version:
4 fiberglass poles (telescopic fishing poles work perfectly).
, which is highly regarded for its focus on practical antenna solutions for constrained environments, such as typical backyards. While Les Moxon is the namesake of the popular Moxon Rectangle hf antennas for all locations moxon pdf
Because the elements are folded, a Moxon antenna is approximately 30-40% smaller than a conventional 2-element Yagi or a standard dipole beam. This smaller footprint allows it to fit into small backyards, apartments, or attic spaces. 2. High Front-to-Back Ratio
| Capability | Benefit | |------------|---------| | | Pre-calculated dimensions for 160m–6m, including WARC bands (17m, 12m, 30m). | | Space-Constrained Variants | "Shortened Moxon" models using loading coils or capacitance hats — with full construction data. | | Portable/Travel Versions | Collapsible, lightweight Moxon designs for SOTA, POTA, and DXpeditions. | | Material-Specific Build Guides | Aluminum tube, wire, fiberglass pole, and even tape-measure versions. | | SWR & Gain Plots | 4NEC2 / MMANA-GAL simulation outputs embedded in the PDF as reference charts. | | Interactive Calculator (Excel/HTML) | Input your available boom length → get custom wire spacing, element lengths, and feedpoint impedance. |
When mounted correctly, it provides the low radiation angle necessary for long-distance (DX) communication. While Les Moxon is the namesake of the
Securely anchor the corner bends. Use an insulating spacer (like a small piece of fiberglass or non-conductive rod) to fix the exact gap distance ( E ) between the element ends.
The critical spacing between the folded tips creates intense electromagnetic coupling. This suppresses signals coming from the rear, often achieving an F/B ratio exceeding 25 dB to 30 dB.
Searching for opens the door to a world of smart, space-efficient antenna design. Les Moxon's original book provided the theoretical foundation, and the antenna that bears his name has proven to be a versatile and highly capable performer, beloved by amateur radio operators worldwide. Its compact size, exceptional front-to-back ratio, and straightforward construction make it an ideal solution for hams facing real estate limitations, seeking a portable Field Day antenna, or wanting a high-performance directional beam without a massive structure. Whether you use an online calculator to model a 40-meter wire version for portable use or a complex four-band beam for your rooftop tower, the Moxon rectangle remains one of the smartest and most satisfying antenna projects a radio amateur can undertake.

Exceptionally wide SWR bandwidth compared to other shortened antennas.
For six months, he fought with a ham stick. He tried an end-fed half-wave thrown into a maple tree. Nothing worked. On 20 meters, he was a whisper in a hurricane. "Sorry, Leo, you're down in the noise," became the hated refrain.
