在整个信息传播领域,中波发射台发挥广播媒介的作用。对于中波发射,在白天,地面充当发射台的传播介质,在夜间,介质变为天波与地面,也就是说,天线地网在中波发射台执行传播功能的主要媒介。因此,要重视天线地网维护工作,这也是保证发射台发挥功能的重要基础。本文分析了中波发射台天线地网存在的不足和问题,对其维护方法进行了全面探讨。 Throughout the entire field of information dissemination, the launch pad has played the role of a broadcasting medium. For mid-wave launches, during the day the ground acts as a propagation medium for the launch pad. During the night, the medium becomes a sky wave and ground, that is to say, the main medium on which the antenna ground network performs its propagation function at the mid-wave launch pad. Therefore, we should pay attention to the maintenance of the antenna network, which is also an important basis for ensuring the launch pad to function. This paper analyzes the shortcomings and problems of the antenna of the neutral wave transmitter antenna and discusses the maintenance methods.
