Simple Ham Radio Antennas--Homebrew 10/20/40m EFHW vertical Antenna "SOTA"


If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/29CA_IPyg9M.  Here's a nice, compact and simple end-fed-halfwave vertical antenna suitable for both home and portable use.  2E0VOV does an excellent job of describing both the theory, design, and operation of this antenna, which is based on the "Par Endfedz" multiband QRP antenna.  The UNUN uses a Ft-140-43 core and is fairly simple to build.  the coaxial feed line acts as a counterpoise, so no ground radial system is needed. While this antenna is a compromise, it does an acceptable job on 10/20/40 meters.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!
