newAn antenna diplexer or RF diplexer is a unit or module that enables two antenna feeds to be combined and carried down one feeder. Conversely, it can act as a splitter to enable the signal from one feeder to be connected to two receivers or antennas.

  • Tetra and mobile antenna diplexer enables Tetra security and Mobile Cellular radio signals to be combined or split with a single feeder.
  • Enabling multiple transmitters to use a single antenna: Mobile services often use multiple frequencies, possibly for different Mobile Network Operators. In view of the size and cost of the antennas they may have a single antenna and they may want to combine the signals from several transmitters to feed into the antenna. As they are on different frequencies, it is possible to use a diplexer to combine the signals and use a single feed.
  • Enabling a multiband transmitter to use different antennas according to frequency.
  • Allowing single feeder to be used for multiple feeds. The signals from he antennas can be combined at the antenna end using diplexer, and a second diplexer at the point of use to route the signals.
