摘要
广播电视站台搬迁或新增调配广播节目时,为节省资源,不同频段节目发射共用同一个铁塔天线时,需要使用多工器。介绍多工器的结构及其工作原理,通过实例阐述多功器的安装与调试,为同行业相关人员提供参考。
In order to save resources,multiplexers are required when radio and television stations are relocated or newly allocated broadcast programmes are transmitted in the same tower antenna in different frequency bands.In this paper,the structure and working principle of the multiplex are introduced,and the installation and debugging of the multiplex are illustrated by examples.
