It is become essential frequently while constructing multichannel sites to combine transmitter band and receiver band into one antenna. "DPS" series bandpass duplexer can handle this task. In DPS5-4V and DPS5-6V each arm represents two- or three-jar 5" coaxial resonator preselector. DPS5-6V duplexer provides wider transmitting and receiving bandwidth, than DPS5-4V.
