某电视台中波发射台的发射塔位置高,周围地广人稀,没有建筑物遮挡。在遇到阴雨、雷电,以及风沙等恶劣天气时,就会使广播播出产生障碍。主要表现为发射机与大地连接,产生反射作用。本文首先介绍了中波发射机产生反射的原理,然后阐述了恶劣天气对中波广播反射产生的影响,在此基础上提出解决恶劣天气对中波广播发射产生损坏的办法和措施。 The launching tower of a TV station, a medium-wave launch pad, is high in location, sparsely populated around it and has no shelter from buildings. In the face of rainy weather, thunder and lightning, as well as sand and other inclement weather, it will make radio broadcast obstacles. The main performance of the transmitter connected with the earth, resulting in reflection. In this paper, the principle of the reflection of the mid-wave transmitter is introduced first, and then the influence of the bad weather on the mid-wave broadcast reflection is explained. On the basis of this, the solutions to the bad weather on the mid-wave broadcast transmission are proposed.
