DAMM TetraFlex® Multi-Tech Outdoor BS422


TETRA, DMR Tier III, TEDS and Analog in one box


Supports VHF and UHF in all technologies


Flexible, cost-efficient solution with up to four carriers in one box


Available for DMR and Analog. Repeater function for TETRA and TEDS


A world first

The world’s only outdoor base station featuring multiple technologies in one single core-connected system: TETRA, DMR Tier III, TEDS and Analog. This technology-independent solution features multiple carriers as well as simulcast in one box within either UHF or VHF frequency ranges.

Core connected!

No more need for gateways or bridges! With the core-connected BS422 you can easily combine multiple technologies in one coherent system. Or choose the one technology that matches your current need – and scale anytime to meet changing voice and data needs with a simple click.

Multiple technologies – one software

With everything covered by one system, operation, maintenance and repairs are simply easy. Multi-technology networks can be managed in a single network management tool with one central subscriber register.  Applications like dispatchers and voice and data log systems can be used across all technologies, and all technologies use the same gateways.

Seamless integration

The BS422 can be set up as a stand-alone system. It can also be seamlessly integrated into any existing DAMM single-tech network such as networks based on DAMM BS421 outdoor and/or DAMM BS418 indoor base stations.

Extended coverage with simulcast

The BS422 enables simulcast for DMR and Analog and also offers repeater functionality for TETRA and TEDS.

Rugged and compact design

The BS422 is built to withstand harsh conditions – from extreme cold to extreme heat and also wet conditions thanks to its IP65 encapsulation. Its compact and light-weight design makes it easy to install everywhere from masts to tunnels and on the back of a truck.

No single point of failure

At the core of the BS422 is a decentralized architecture, which ensures that all system information is constantly replicated to all sites in the network. This means that the system does not have any single point of failure.

This way, local call and data traffic will run without interruption, even if one site loses its connection to the rest of the network.

Flexible and future-proof

The flat decentralized IP architecture and intuitive software also enable effortless, self-configuring site expansion. The BS422 can be used with single or multiple carriers as well as single or multiple technologies, giving you maximum flexibility.
