Designed for the decoupled combining of 2 transmitter or

receiver signals onto one common antenna.


The frequency spacing between transmitter signals can be

as small as required.


Excellent intermodulation performance.


Wall or 19´´rack mounting.


DC by-pass between port 1 and port 3.


External DC stop available as an accessory.

For indoor use only.


The input power rating of 150 W per port is specified at an ambient

temperature of +55 °C with the combiner mounted vertically (see

photo), without additional cooling, and while respecting the safety

standard EN IEC 60950 (max. surface temperature +90 °C).

When installed in a 19´´ rack, it must be ensured that the max.

power of 150 W is sufficienly dissipated, so that the ambient

temperature does not rise above +50 °C. This can be achieved

for example by the additional installation of a correspondingly

dimensioned ventilator in the 19´´ rack or by reducing the

maximum input power.
