Splitter per HF
Se fornisco a due ricevitori il segnale captato da un’antenna attraverso un coassiale a 50 Ohm per tramite di un connettore a T, capiteranno delle cose strane, spesso prevedibili

Antenna splitter for Broadcast and 144 MHz
The center frequency 91 MHz of the FM Broadcast cut-of is more then 40 db and on 145 MHz the attenuation is quasi 0 db
Antenna splitter per VHF-UHF per quattro ricevitori
Chi dispone di una sola antenna e vuole collegarvi più di un ricevitore necessita di uno splitter
Build a 2-Meter Duplexer repeater
Cavities, Diplexers, Duplexers, Theory, and More
Combiner and Splitters
The magic T combiner or splitter is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads
VHF-UHF Diplexer
Diplexer is a special filter circuit that seperates 2 different bands. It is different from Duplexer which seperates 2 frequencies on the same band

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
