Procom DPF UHF/33-DR 3000

The DPF UHF/33-DR 3000 is a 6-cavity duplex filter designed to be built into the Motorola DR 3000 duplex base station/repeater.
The DPF UHF/33-DR 3000 can be adjusted within the complete
 406 - 470 MHz band. The duplexer can delivered with a 5 - 16 MHz spacing.
The DPF UHF/33-DR 3000 is primarily intended for TX and RX operation on single frequencies, but it can also, however with slightly reduced data, be used where the TX and RX operate on several channels, i.e. within a certain port bandwidth. In the latter case, factory tuning is recommended.
The filter uses full-length ¼ λ cavities in a compact, extruded aluminium housing. The chassis is made of passivated steel, and teflon insulation has been applied in the coaxial cables and in the connectors.
The filter is coated with black vinyl to prevent corrosion.
