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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
