Antenna verticale multibanda con semidipoli
This type of antenna, because of the length limitation of the support, can satisfy the need of three bands: 14, 21 and 28 MHz a fourth conductor could find a place on the support in the future

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
