Introduction: The ZHC929G-25W FM tunneling remote unit cooperates with a leaky cable or a transmitting antenna to fill the blind area and extend the coverage of the transmitting station. Mainly used in road tunnels, underground parking lots, subway tunnels and station halls, civil defense facilities, schools, and so on. Features: 1. It adopts integrated aluminum alloy to efficiently dissipate heat, and the fully sealed structure has dustproof, anticorrosive and moisture proof functions; 2. Adopt high linearity power amplifier circuit and high performance output filter circuit to effectively reduce intermodulation and out-of-band products; 3. Adopt fiber optic module with AGC power and RF amplification module to ensure stable output power; 4. Each stand is subjected to strict high temperature aging before leaving the factory, and the reliability is very high; 5. The built-in SMS module can be used for real-time mobile phone remote monitoring and control, or multiple units to form a centralized monitoring system; 6. With TCP / IP network interface, both remote monitoring and control, as well as firmware upgrades. (The functions of remote control through SMS and network port include: switching machine to adjust output power; parameters monitored include: output power, reflected power, operating temperature, working current, working voltage and input optical power are within the normal range, when the above parameters An alarm signal is issued when the normal range is exceeded.)
