Simple Ham Radio Antennas--End fed portable all band dipole setup and 150W matchbox 9:1 unun


If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/IQVTnKQuKaM.  Here's another interesting, portable multiband HF antenna from "nelson antennas."  The key to this handy and easily useable antenna is the matchbox with an internal 9:1 unun transformer made with 20 gauge wire in a trifilar winding.  The antenna wire can be a  arranged in a sloper, vertical, or inverted L configuration with one lead connected to the antenna bolt and the ground radial or counterpoise system connected to the other bolt.  In this video, the transceiver is a Yaesu FT-897D and the antenna transmatch (i.e. "tuner") is a LDG-YT 100.  If you don't want to make your own 9:1 unun, you can go to "nelson_antennas" on eBay.  The eBay identification number is 191226640113.  Good luck!
