DPR4-4U is a classical band pass-reject duplexer for manufacture of single-channel UHF, separation between receiving and transmission frequency here is 5-10 MHz, repeater. Duplexer narrowband characteristic provides higher selectivity of repeater receiving section and attenuates transmitter out-of-band radiation better, than in common mobile duplexer case.
