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 alexanderball50@bigpond.com
