摘要
天馈系统改造是为了提升信号质量,提升了广播和电视节目的播出质量,而双馈系统是能够高效快速地实现网络间切换,不间断且高质量地将信号传送出去,为广播电视安全播出提供有力保障。该文以宁夏广播广播电视台下属中波台为例,比较了天馈系统改造设计方案,阐述天馈系统的原理与天馈系统改造工程的实施,希望能为其他中波发射台的天馈系统改造提供参考。
The transformation of antenna feeder system is to improve the signal quality and the broadcasting quality of radio and television programs.The doubly feeder system can efficiently and quickly realize the switching between networks and transmit the signals continuously and with high quality,so as to provide a strong guarantee for the safe broadcasting of radio and television.Taking the medium wave station subordinate to Ningxia radio and television station as an example,this paper compares the transformation design scheme of antenna feeder system,expounds the principle of antenna feeder system and the implementation of antenna feeder system transformation project,hoping to provide reference for the transformation of antenna feeder system of other medium wave transmitting stations.
