摘　　要：天线调配网络在中波发射台中介于发射天线和发射机中间,起适配和管道作用,事关安全播出长期稳定性。它的结构组成、基本特点、设计与实现、计算验证等值得探讨,特别是各个关键点位的计算是天线调配网络中的难点。本文结合昆明实验台4号塔实际情况展开理论验算。The antenna deployment network is between the transmitting antenna and the transmitter in the medium wave transmitting station,which plays the role of adaptation and pipeline,and is related to the long-term stability of the safe broadcasting.Its structure,basic characteristics,design and implementation,computation and verification are worth discussing,especially the calculation of each key point is a difficult point in the antenna deployment network.In this paper,based on the actual situation of Kunming Test Station Tower 4,the theoretical calculation and thinking practice are carried out.
