How to build and tune a half-square antenna
Thanks to Charlie of the "Red Summit RF" youtube channel for this practical guide to building and tuning a simple half-square antenna. In this video, Charlie takes us step-by-step through the design, building, and testing procedures for this 20 meter DX antenna.

Here are some additional comments from Charlie: I take you through my steps to build this 20 meter DX antenna, including construction of the insulators, and a trip into the field to tune it up. "In the field" turned out to be a RUSS event (Radio Under the Sun Shade) which is basically a Radio in the Park in my area that is held once a month.
