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.

Here are a few comments from Alex (VK2PRC):
A complete step by step guide for, making and tuning a 20 Meter HWEF vertical antenna including impedance matching coupler. 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 other size!!!!!!! The common mode toroids are FT114 core mix 43 MY EMAIL email@example.com
Thanks for joining us today.
