Antenna yagi3 elementi per i 50 Mhz
L'antenna e' ottimizzata per il massimo guadagno e rappresenta il massimo che puo' essere ottenuto con un boom di soli 0,4 lambda
Bicycle Rim Magnetic Loop for 6m
Cap modification for 20m to 10m, good for 100W+
BV6 Yagis-yagis for 6m
Here are two yagis for 6m, one 1 wavelength long with a gain of 9.5dBd, and the other a 2.1wl model with a gain of 11.8dBd
Coaxial-Dipol antenna consisting of an antenna whip
This is a very simple antenna consisting of an antenna whip of 1/4 wavelength and a tube of 1/4 wavelength

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
