VK2 PRC Half Wave End Fed Vertical-20m Antenna for DX.
Thanks to Alex (VK2PRC) for this in-depth review of end fed half wave antennas. In this video, Alex takes us step-by-step through the design, building, testing, and use of a 20 meter end fed half wave antenna. Alex reviews the theory behind vertical half wave antennas and explains why a matching transformer is necessary to insure optimum performance.

If you are unable to make one for yourself, email me and I'll make one for you. I am now also offering a more efficient coupler design that incorporates a 20M HWEF and a 1/4 wave ground plane 40M antenna feed point in the one box. See my second video in this series or Contact me for details. NOTE: 1mm enameled wire MUST be used, NO
