Constructing multichannel sites it is become essential frequently to combine transmitter band and receiver band into one antenna. "DPS" series bandpass duplexer can handle this task. In DPS8-4V and DPS8-6V each arm represents two- or three-jar 5" coaxial cavity preselector. DPS8-6V duplexer provides wider transmitting and receiving bandwidth, than DPS8-4V.
