Apply to UHF interphone communication system or TETRA digital trunking communication system signal coverage extension. This is also known as “UHF wireless BDA”.
Product Features：
☞Advanced and scientific design of low noise circuit, high sensitivity
☞ALC Automatic Control and reflex protection circuit，prevent accidental burnout
☞Adopting advanced LDMOS power amplifier with high linearity and low intermodulation, the linearity and intermodulation indexes of whole machine are excellent
☞Perfect Local and remote network monitoring, has initiative alarm function, and parameters can be inquired and set.
☞Supply charging power and backup battery to ensure fault information timely report in time of machine outage, convenient for timely maintain,
☞Crate accord with IP55 protection and high heat-dissipation design, able to work outdoor all-weather.
