Antenna da 1.8 a 28 m
Come costruire un'antenna da 1.8 a 28 Mhz utilizzando una canna da pesca in fibra di vetro lunga 10 m

Antenna Vertical Links →
Vertical half-wave aerials for 4m
For vertical use, it is much more mechanically convenient to end-feed an antenna: this will allow it to be mounted higher, and avoids distortion of its omnidirectional polar
Vertical Pancake Dipole 10-20 Meters
The antenna easily loaded 10-20 meters in the vertical configuration but it didnt do well for me on 10 and 17 meters as a horizontal dipole
Verticale con riflettore
Queta antenna l'elemento riflettore ed i radiali son isolati da massa

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
