The DAMM MultiTech Outdoor Base Station
BS422 is a multi-carrier, multi-technology
outdoor base station. It comes in two versions:
the standard BS422-S version and the BS422-
SP with a built-in AC mains power supply. Both
variants act as a complete system integrated
into one box, including switching functionality,
network management, gateways and other
decentralised system components.
They can operate up to four carriers, each in
any technology mode:
• TETRA
• DMR
• Analog
Multiple carriers and technologies in one
base station
Each BS422 can contain up to four carriers,
and thanks to the multi-technology design it
is possible to run a different technology on
each carrier, i.e. DMR, TETRA or Analog. Our
core-connected design ensures seamless
interoperability between the different
technologies, delivering maximum flexibility for
any kind of application.
Full integration in the DAMM
®
System
Both the BS422-S and the BS422-SP are
fully integrated in the DAMM system and
support all applications and features known
from our single-tech product line. Customers
can seamlessly extend existing single-tech
networks with the new MultiTech product lines
while benefitting from the new options like
mixed operations of TETRA, DMR and analog
modes.
Best-in-class RF handling
The BS422-S and BS422-SP are provided
with dual receiver diversity, offering outstanding
sensitivity and have a built-in duplex filter.

MultiTech Outdoor Base
Station BS422-S and BS422-SP
The innovative design enables high transmit
power in a very compact design, improving
the coverage while keeping the operational
costs low. The maximum transmit power varies
between the different technologies.
Wide frequency ranges from the 80MHz to
the 800MHz band, independent of operation
mode, allows for agile spectrum adaptation no
matter if it is in TETRA, DMR or Analog mode.
The built-in GNSS antenna – which is also
suitable for Galileo and GPS satellite signals
– makes the installation process simple and
cost efficient. However, if preferred an external
GNSS antenna can be used as well.
Flexible installation, even in harsh
environments
The outdoor base stations are designed to
be mounted in the top of a mast close to the
antennas. This eliminates the traditional TX and
RX signal degradations due to feeder loss and
reduces the cost considerably.
The BS422-SP with its built-in AC power
supply provides an exceptional, cost-efficient
single-box solution when a service box is
not required. It is either AC or DC powered
and therefore a perfect match for the DAMM
Transport Box TB422.
Both variants are designed for harsh climatic
environmental conditions, are IP65-protected
and can installed in almost any environment
where it is required.
