Combiners (Network Combiners)


Rojone has designed a number of combiners to customer specifications or application requirements. Notably one of the most popular combiners is our Multi-Network combiner providing 4 Input ports and 4 Outputs together with a monitor port for in-building applications.

Multi-Network Combiners 800-2500MHz

This fully integrated Multi-Network Combiner Module was designed specifically for in-building applications. This combiner accepts up to 4 networks into a distributed antenna system and offers 4 identical RF output ports.

Particularly within in-building applications where power budget is a limiting factor, this combiner design directs all RF energy into the Distributed Antenna System instead of dissipating power through multiple stage loads. This solution allows multiple sectors to be combined into one single sector for better trunking efficiency and frequency planning.

The module’s integrated design is configurable from 1 to 4 inputs and from 1 to 4 outputs. Unused input ports are broadband terminated using low power loads; unused output ports must also be broadband terminated using high power 100 watt loads to assure optimum performance.

Installation is easy; the combiner is provided with a robust mounting flange, ideal for wall mounting. All ports are low IM Female N connectorised and are easy to access. Our combiner also features a 30dB monitor port allowing for on-line hot system testing.
