无线发射台的信号传输都是通过天馈线系统来完成的,因此天馈线系统安装质量和运行情况的好坏将直接影响到节目质量、无线信号的覆盖和接收设备的工作状态。当发射天馈线发生故障时,发射信号将会产生损耗,从而影响台站的覆盖范围,若发射天线出现的故障较为严重时,发射机设备会因驻波保护关闭,当接收天线发生故障时,则其接收监测的信号将会减弱,从而影响对设备的工作状态的判断。
The signal transmission of the wireless transmitting station is accomplished through the antenna feeder system. Therefore, the installation quality and operation of the antenna feeder system will directly affect the quality of the program, the coverage of the wireless signal and the working status of the receiving equipment. When the transmitting antenna fails, the transmitted signal will have a loss, which will affect the coverage of the station. If the transmitting antenna is more serious, the transmitter equipment will be shut down due to standing wave protection. When the receiving antenna fails, The signal it receives and monitors will be weakened, thus affecting the judgment of the working state of the device.
