1故障想象机器过荷保护,无法工作。2检修从现象上看,处于全反射状态问题可能是出在天线及连接头上。因此,首先检查发射机荷馈线的连接处,没有发现异常,用摇表测的电缆头芯地间处于短路状态,拧开馈线及天线连接头再用摇表测天线为短路。该天线是开路天线,短路说明天线有问题,拧下电缆与天线的接头螺丝后,发现天线钢管底部有水,且水覆盖了馈线与振子的接线柱,
1 failure to imagine the machine overload protection, unable to work. 2 Maintenance From the phenomenon point of view, in a state of total reflection may be out of the antenna and the connector. Therefore, first check the transmitter load feeder connection, did not find anomalies, measured with a shake table in the cable core between the short-circuit state, unscrew the feeder and antenna connector and then shake the table to measure the antenna for the short circuit. The antenna is an open antenna, the short circuit shows a problem with the antenna, unscrew the cable and the antenna connector screw and found that the bottom of the antenna tube water, and water covered feeder and vibrator terminals,
