目前在铁路上广泛使用的 IC- 751短波电台通常使用水平天线 ,它的主要指标除方向性系数、天线效率、增益系数、天线仰角外 ,在日常检修中还要考虑天线环阻、线间阻抗、接地电阻及对地绝缘电阻等。这里就实践中出现的天线绝缘不良对通信的影响作一浅析。某个分局听路局电台信号 At present, IC-751 short-wave radio stations widely used on railways usually use horizontal antennas. The main indexes of the IC-751 short-wave radio stations are the directional coefficient, antenna efficiency, gain coefficient and antenna elevation angle. , Grounding resistance and insulation resistance and so on. Here on the practice of the emergence of poor insulation of the antenna to make a brief analysis of the impact of communications. Listen to a bureau station radio signal
