Delta loop de 5 elementos para 50mhz
Use its impedance adapter, the adjustment has no problem and the ROE is usually 1: 1.1 out of 50.100 which is the center of the band
Delta Loop 3 elementi 50 MHZ
Viene elimentata direttamente da cavo coassiale a 50 OHm
Dipolo per i 50MHz
Dipolo ripiegato realizzato con del cavo coassiale a 50 Ohm
Direttive HB9CV per Band 50Mhz
The mechanical construction is a little bit difficult for the phasing lines and you need a compensation-C for tuning the SWR

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
