This diplexer allows simultaneous use of two UHF SATCOM Transceivers (200 Watts per channel) with one antenna. No TX/RX switching, isolation between TX & RX bands takes place through custom filters ensuring compatibility with all of the fast switching communication modes. Ability to power the unit through local power connection or through the Radio 1 RF Connector via a Bias “T” circuit (9-28 VDC input). Great for use on Maritime Craft, Vehicles, Base Stations and other platforms that are limited for antenna space.
