A duplexer lets one antenna carry both the transmitter and the receiver at once. Without it, a repeater needs two antennas far enough apart that the transmitter does not deafen its own receiver, which on a vessel or a coastal station means a second mast position that is rarely available.

Six cavities are tuned to the marine channels the station will actually run on, which is why they are asked for at the time of order. The filter is rated for 50 W and works from −30 °C to +60 °C, with BNC-female connectors on all three ports.

Also available for other bands: VHF 144-175 MHz, VHF 68-88 MHz and UHF 400-470 MHz. Mounting plate MP002 is ordered separately. Contact sales for special solutions.
