406MHz to 512MHz Duplexers











 | Overview


Base/Mobile Duplexer with very low insertion loss(0.6dB typ.) and high isolation(85dB typ.)

World class engineering incorporated in the design for people with concerns about size and space.


  • Base station performance in a mobile size package.
  • High isolation with very low insertion loss are standard features.
  • Specifically designed for people with concerns about size and space.
  • Multiple units fit in same space required for regular units from other suppliers.


                                                                  Typical Applications



                                                                - Base Station Repeaters

                                                                - Mobile Repeaters

                                                                - GMRS Repeaters

                                                                - Amateur Radio Repeaters
