Bi-Plane Antenna for 20 Meters


A Bi-Plane antenna for 20 meters, tuned it up, and put it on the air. Resultsd indicate that it is working pretty well for a 3-feet long dipole-type antenna at 22 feet up

10 elements en V inverse pour 14MHz
An antenna of this type provides only one direction and cannot be moved, so I decided to test it during the Russian District Award Contest
