An 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 400 / Mobile Diplexer

Diplexer 400 Tetra / Mobile

• 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.

We have a TETRA system from Motorola which we would like to sell.

These are used by police and security forces worldwide. Some proerty management groups will use them too. These are like walkie talkie radio but they are digital and they have data communications capability.

The system we are selling has 3 cell sites and 200 subscribers. Condition is excellent.
