This video is part three of four segments showing how to build a backyard HF vertical antenna. Kevin Loughin (KB9RLW) does an excellent job of taking us from antenna concept and design to actual construction and testing of this simple, efficient HF antenna. In part 1, we get an overall plan for the antenna; in part 2, we begin building the 9:1 UnUn; and in part 3, we learn how to make a 1:1 common mode choke to keep stray RF off the feed line. Part 4 will integrate all parts of the antenna into a final building project for the vertical antenna.
