调频天线馈线系统扩容的解决方案

Solution to Expansion of FM Antenna-Feeder System

随着调频广播的发展,天馈线系统扩容与发射塔的天线安装空间有限的矛盾,成了制约调频广播发展的突出问题。能否利用已有的发射塔资源,达到天馈线系统扩容的目的,是本文所要讨论的问题。选用不同的天线形式,进行安全合理的施工设计,以及采用大功率天馈线系统是我们提出的解决方案。

With the number of FM broadcast pograms increased, the power capacity ofexisting FM antenna-feeder system in various regions, particularly in large and middle-sized cities cannot meet the requirements of development. And building a newantenna or a new tower faces many a difficult problem; thus the expansion of the FMantenna-feeder system remains unsolved for many years. There is proposed thefollowing solution: Adopt a high-power antenna-feeder system with a safe and rationalconstruction design using existing transmitting tower resources and a differentantenna form. This is believed to be of some reference value to insiders.
