Tri-Band 20m 30m 40m Ground Plane Antenna. Post #1366.
If you can't view this video, please insert this title URL into your browswer search box: https://www.youtube.com/watch?v-hZ6i2wqa8vo. Interesting video from AB8XX--something he calls a "parallel ground plane antenna." The antenna is a basic ground plane with radiating elements for 20m , 30m, and 40m separated with PVC tube spreaders. The antenna is suspended from a 60-ft/18.29 m tree branch with the feed point about 20-ft/6.09 m above ground. AB8XX fires his antenna into neighboring trees with a super powered launcher. The antenna performs well on the bands specified.
