I found the steps taken to prevent the thinnest part of the pole from collapsing into the interior section of the mast most helpful.  A simple cored loop will keep the tip of the mast from "getting lost.'

In this video, Kevin reminds us that this installation is only experimental, subject to final testing and a thorough review of safety precautions before we turn on our HF transceivers. So, how does this antenna work?  According to Kevin, "It's finally up and working...And working very well!  I've made many contacts on it an had the best signal reports I've ever received, especially on 75-90 meters." If you have limited space and little cash, you may want to try this simple, efficient,

If you can't view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=9kY2rz2jizs 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.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=VAV9Wws-Bs0 This is part 2 of Kevin Loughin's (KB9RLW) backyard vertical antenna project.  In part 1, Kevin outlined the design and construction parameters for this simple, effective antenna. In part 2, Kevin shows us how to build the 9:1 UnUn for the antenna.  Kevin takes you step-by-step through the building process so you won't make a mistake in putting the UnUn together.  Kevin will integrate these parts into the full antenna in parts 3 and 4.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=-AjsRoajjO8 This well-made video tutorial from Kevin Loughin (KB9RLW) is part one of a four-part series on the design, construction, tuning, and use of a homemade HF vertical antenna.  Part one of this series discusses the design and plan of the HF vertical, while part two shows how to build the 9:1 UnUn and 1:1 current balun used for the antenna.  Kevin does an excellent job of taking us step-by-step through the entire design and planning process.  Subsequent videos will refine the design and show us how to get on the air with this simple, effective antenna.
