The definitive resource, often holding PDF guides, design formulas, and calculators for various bands from VHF to HF.
With a 40-meter version taking up only about 50 feet of width, the Moxon is often the only way to get a directional, gain-producing antenna into a small backyard, while a Yagi would require 67 feet. Conclusion hf antennas for all locations moxon pdf
○ Suburban backyard (full size) ○ Townhouse / small lot (shortened) ○ Apartment balcony (bent / indoor) ○ Portable / Field (collapsible) ○ Marine / RV (mountable on metal)
The dimensions below are representative for a basic design, using common specifications for clarity. These are provided as a general guide; always use a specific calculator for your exact frequency, wire diameter, and materials. These are provided as a general guide; always
Building a stealth wire version for upper HF bands (10, 12, or 15 meters) keeps the physical dimensions small enough to fit inside attics or along balcony railings. 2. Portable, SOTA, and POTA Operations
Connect an antenna analyzer to the feedline. Look for the lowest SWR point. Portable, SOTA, and POTA Operations Connect an antenna
The antenna suppresses radiation from the rear. This produces a high front-to-back (F/B) ratio, often exceeding 30 dB. Environmental and Location-Specific Adaptations
Using thin, jacketed wire colored to match the background (sky or trees) makes the antenna virtually invisible from the street. Portable and Field Day Operations
