SRB250 P25 Rapid Deployment Repeater

The Simoco SRB250 is a transportable rapid deployment repeater that is designed to provide radio coverage to a critical incident, emergency situation or extends existing Public Safety systems, either analogue or APCO Digital P25. It provides deployable “on demand” coverage for vehicle and portable radio users in VHF or UHF. It is an ideal solution to keep public safety and government agencies connected.
