Antenna 20mt 14 Mhz Links →
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
20 meter hamstick mini beam project
Element kits to be mounted so the elements are at 90 degrees from one another, the antenna was resonated to 14250 Khz
20m Delta Loop
The diagram above depicts the 17 and 20 meter delta loops setup
Dipolo rigido echo 10-15-20
Dipolo rigido 10-15-20m, balun con toroide T-157-6, filo smaltato da 1mm
20m mini loaded dipole
This is my "mini dipole" for 20m that I built to have some fun while in holidays
