A 20 meter Moxon Antenna

A 20-meter Moxon antenna design provides a compact directional solution for the 14 MHz band, achieving approximately 5.5 dBi of forward gain and a front-to-back ratio exceeding 20 dB. This rectangular wire array, consisting of a driven element and a reflector, offers a smaller footprint than a traditional 2-element Yagi, making it suitable for space-constrained installations.

Construction details focus on specific dimensions for the wire elements, fed with 50-ohm coaxial cable. The Moxon rectangle inherently delivers wide bandwidth and a clean radiation pattern, simplifying tuning with a relatively low SWR across the entire 20-meter band. Its robust performance makes it a practical choice for both fixed stations with limited tower space and portable DXing operations.

The design's characteristics are particularly beneficial for contesting and long-haul communications on 20 meters.
