We suggest you to utilize DPS4-4A and DPS4-6A duplexers, if you are planning to construct multichannel 300 MHz repeater but unable to install two separated antennas. It will provide, together with wide-band D or DS series antenna, operation of repeater at standard duplex separation of 36 MHz and will easily pass transmitting and receiving frequency bands. In DPS4-4A and DPS4-6A each arm represents two- or three-jar 4" coaxial cavity preselector. DPS4-6A duplexer provides wider transmitting and receiving bandwidth, than DPS4-4A.
