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 ports allowing for on-line hot system testing.

This is a 4 Input / 4 Output Combiner Network – Any UNUSED PORTS MUST BE TERMINATED. 

Unused Input Ports will be factory terminated with Medium power Loads.
Unused Output Ports will be factory terminated to our Integrated High Power 3 in 1 Load. 

This is our standard configuration.  Should you wish to use an Input or Output port later in the product’s life, you simply need to remove the loads to add a Telecommunication’s carrier to the Input and/or add another antenna to the combiner’s output up to a total of 4 input and 4 outputs. 

* Should you choose to either use all 4 inputs and 4 outputs or supply your own loads, the combiners order code would simply be ROJ065-4-4.

The integrated 3 in l high Power Load is supplied complete with a cooling fan.  This fan must be operational 100% of the time to ensure that the load does not overheat.
