RM120

The RM120 is a compact roof mount system which incorporates the drive control, positioning hardware and HPA into the antenna housing making the RM120 a robust, stand alone assembly, ready to mount onto almost any vehicle.

The versatile power payload of the RM120 has been designed to take low power SSPA's mounted on the feed arm for reduced loss or high power TWT's in single thread or redundant configurations with power levels up to 400w.

The satellite acquisition controller uses industry standard position transducers and a sophisticated pattern recognition algorithm to confirm and refine it's heading information using visible satellites.
.
The controller is mounted within the antenna mounting structure with a separate power supply and control panel which can be either rack mounted or a simple hand held unit.

The system is simple to install, set up and use.
Following relocation of the antenna, the system will reliably and accurately locate and lock-on to the designated traffic satellite within a couple of minutes.
