Description
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.
- A wide range of frequency bands is available
- Individual channel programmable parameters, including frequency, power, NAC/TGID, RF mode and channel bandwidth
- Optional feature upgrades are available using software keys
- Easy to deploy base station with intuitive setup and simple remote management
