摘要
针对高山广播电视发射台的驻波比问题进行深入研究。分析当前存在的高驻波比问题的原因及其危害,提出一系列降低驻波比的方法,包括天线选择与优化、馈线系统改进、阻抗匹配应用以及定期维护与检测等。通过实例分析,验证这些方法的有效性,为提高广播电视发射效率和信号质量提供理论依据和技术支持。
In this paper,the problem of standing wave ratio of high mountain radio and television transmitting station is studied deeply.This paper analyzes the the causes of high standing wave ratio and the hazards,then puts forward a series of methods to reduce the standing wave ratio,including antenna selection and optimization,feeder system improvement,impedance matching application,regular maintenance and inspection.The validity of these methods is verified by an example analysis,which provides theoretical basis and technical support for improving the transmission efficiency and signal quality of radio and television.
