40/30/20m Short Vertical Antenna
This paragraph is about how I added" 30 meters to my 20/40 meter short vertica
Antenne verticale fusil a 3 coups
It is a vertical multiband antenna composed of several radiating elements lambda / 4 length fed by a single coaxial cable
Antenne verticale monobande 7MHZ
If the tower can not be isolated from the ground it will be necessary to feed it using a gamma-match
Bigger Multiband Vertical 160-30mt
