Manufacturer: Selex Communications  
Product type: C4ISR  
Name: Radio station  

The CNR-2000 Family is a new line of Selenia Communications HF/VHF (1.6 MHz to 60 MHz) multiband ,multirole, multifunction tactical radio communication transceivers embedding within a single package the capabilities for different operational roles in the battlefield.

Operation over the extended 1.6 MHz to 60 MHz frequency range allows short/medium/long haul communications over LOS (Line Of Sight),ELOS (Extended Line Of Sight) and BLOS (Beyond Line Of Sight) links with HF and VHF tactical radios.

The open system,software programmable architecture of the CNR-2000 family allows the expansion/customisation of capabilities to meet specific requirements and a progressive evolution towards future configurations of the 21st Century tactical radio,in line with the requirement for full integration of lower-echelon field units into the Command and Control System.

The CNR-2000 equipment have embedded facilities for operation as elements within radio networks and as radio communication components interfacing with wired communication systems,providing:

  • Situational awareness using GPS positioning data

  • CNRA (Combat Net Radio

Access) services,such as addressed call facilities between CNR-2000 users and connection to external tactical and infrastructure networks.

EPM protection can be provided by a TRANSEC/COMSEC proprietary scheme implemented as an EPM internal SW module.

STANAG-4444 will be implemented as a future enhancement of the HF EPM capability.

The CNR-2000 Family includes the following equipment:

  • SRT-178/M 25W HF/SSB - VHF/FM 10W for manpack use

  • SRT-178/VM 25W HF/SSB - VHF/FM 10 W for vehicular installations

  • SRT-278/VM 125W HF/SSB - VHF/FM 50 W for fixed/semifixed installations with external High Power Amplifier and Antenna Tuning Unit

The primary role of the SRT-178/M is to operate as a Combat Net Radio in voice/data wireless networks in the Forward Area, providing connection between group members at different levels.

These capabilities mean unconstrained mobility,operational flexibility and quick deployment in the tactical battlefield.

The SRT- 178/VM and SRT-278/VM are primarily intended for deployment in vehicular,sheltered or fixed Command Posts.

All the above three configurations, are built around a common Receiver/Exciter Unit which is associated with:

  • a built in RF Power Amplifier suitable for rated RF power level

  • a built in Automatic Antenna Tuning Unit capable of matching a wide selection of tactical whip and wire antennas and mounting hardware specific to the type of


The vehicular transceiver is designed for operation from the vehicle's battery while the SRT-178/M is provided with a rechargeable battery pack contained in a battery case secured to the Transceiver package (there is a choice of different battery types).

The user friendly Man Machine interface allows the selection of the operational modes by unskilled personnel on the field.
