摘　　要：调配网络作为阻抗变换器连接于发射机与天线铁塔之间,使中波发射机对应频率信号能以最大功率辐射出去。当发射机频率相近时,需要在调配网络中加入相应频率的阻塞网络,从而减小广播频率的串扰,保护发射机。基于此,阐述几种天线阻塞网络的特点及其应用环境,结合实例进行讲解与分析,为设计人员设计阻塞网络提供相应参考。The deployment network is connected between the transmitter and the antenna tower as an impedance converter,so that the corresponding frequency signal of the medium wave transmitter can be radiated with maximum power.When the transmitter frequency is close,a blocking network with corresponding frequency needs to be added in the allocation network to reduce the crosstalk of the broadcast frequency and protect the transmitter.This paper mainly describes the characteristics and application environment of several antenna blocking networks,and explains and analyzes them with examples to provide corresponding reference for designers.
