If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=VXo0XucRpt0. Here's another simple, "no solder-assembly-required" portable/emergency HF vertical antenna fed with homebrewed feed line. NG9D calls his creation a "3-band lambda antenna", because its shape resembles the Greek letter "lambda." The antenna covers the 20 meter, 30 meter, and 40 meter amateur radio bands and requires an ATU (automatic tuning unit) and small counterpoise to attain decent efficiency. The vertical element is 34-feet/10.36 meters long, while the "counterpoise" wire is 17-feet/4.57 meters long. The video does a good job of explaining the theory and general operating techniques behind this remarkably simple, easily-made antenna.
