TETRA base station

DIB-R5 outdoor

The DIB R5 outdoor is the ultra compact variant for use outdoors or in particularly harsh environments. It guarantees minimum operating costs with reliable radio coverage.


Compact and space-saving

The Outdoor base station has a maintenance-free, space-saving design and can be installed on walls, antenna masts or in tunnels.

Thanks to its market-leading low power consumption and passive cooling, it is ideal for use in areas where power supply is critical or where there is a need for battery-based, portable base station solutions.


Market-leading energy efficiency

Very low power consumption and passive cooling – ideal for areas where power supply is critical or battery-based , portable base station solutions are demanded.


Robust and reliable

Especially in harsh areas the users communication depends on a realible system, therefore the DIB-R5 is a good choice. Comply with the high dust and waterproof standard IP65, the functions confront harshest environments by -30 to +55°C.
