A tree friendly 2 Meter halo Antenna
I decided I needed a horizontal polarized antenna
Antenna halo per i 2 metri
I present the halo for 2 meters. The halo is an omnidirectional polarized horizontal antenna
Antenna halo 144 MHz
Halo antenna che nella versione per i due metri sta tra le nostre braccia e quindi praticamente 1entra senza problemi in uno zaino
The square pole antenna
The Square-pole is a 1/2-wave dipole that has been bent into a square.This is the principle of the Squalo

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
