SB2025NT-C P25 Base Station

SB2025NT Base Station

SB2025NT-C Compact P25 Base Station

The SB2025NT-C Base Station offers market leading dual mode P25 conventional and analogue performance in a robust, reliable yet compact 2U form factor. Designed and built to exceed industry standards, this base station features a digital fixed station interface (DFSI) enabling economic deployment and simple remote management.

Performance & Reliability

The combination of advanced component surface mount technology, rugged machined module casing and optimised PA heatsink, ensures that the SB2025NT-C base station offers outstanding performance and reliability under the harshest conditions.

The sensitive receiver features a wide switching bandwidth while maintaining good blocking, intermodulation and adjacent channel performance. The broadcast transmitter exciter module has very low spurious emission levels, and is followed by an efficient RF power amplifier.

  • Wide range of frequency bands available
  • Individual channel programmable parameters, including: frequency, power, NAC/TGID, RF mode and channel bandwidth
  • Optional feature upgrades available using software keys
  • Easy to deploy base station with intuitive set up and simple remote management
