Hybrid Combiner
8 : 4 / 8 : 4 / 12 : 4 / 16 : 4
• Designed for the decoupled combining of 8/12/16
transmitter or receiver signals and distributing these
signals evenly onto 4 antenna outputs.

Note:
The use of fewer than 8/12/16 inputs or 4 outputs is possible. Any unused input ports have to be terminated with low-power
50-Ohm loads (e.g. Kathrein type 78410367), unused output ports have to be terminated with high-power 50-Ohm loads
(e.g. Kathrein low intermodulation type 78210474).

Please Note:
The installation team must be properly qualified and also be familiar with the relevant national safety regulations.
The details given in our data sheets have to be followed carefully when installing the combiners and accessories.
The limits for the coupling torque of RF connectors, recommended by the connector manufacturers must be obeyed.
Any previous datasheet issues have now become invalid.
