Description:
Apply to TETRA digital trunking communication system (TETRA, GOTA, and IDEN) signal coverage extension.
Product Features:
1.Advanced and scientific design of low noise circuit, high sensitivity
2.ALC Automatic Control and reflex protection circuit, prevent accidental burnout
3.Adopting advanced LDMOS power amplifier with high linearity and low intermodulation, the linearity and intermodulation indexes of whole machine are excellent
4.Perfect Local and remote network monitoring, has initiative alarm function, and parameters can be inquired and set.
5.Supply charging power and backup battery to ensure fault information timely report in time of machine outage, convenient for timely maintain,
6.Crate accord with IP55 protection and high heat-dissipation design, able to work outdoor all-weather.
