卫星接收天线在节目传输系统中的应用及日常维护

Application and Routine Maintenance of Satellite Receiving Antenna in Program Transmission System

近年来我国国民经济发展迅速,人均可支配收入日益提高,有线电视系统走进千家万户得到应用和普及,越来越多的人们选择收看卫星有线电视节目。然而卫星接收天线需要置于户外,长期经受风吹日晒。因此,如何提高卫星接收天线的应用率以及对其进行日常维护已成为当前十分重要的研究课题之一。

In recent years, with the rapid development of China’s national economy and the increasing per capita disposable income, the cable TV system has been applied and popularized in thousands of households, and more and more people choose to watch satellite cable TV programs. However,the satellite receiving antenna needs to be placed outdoors and exposed to the sun and wind for a long time. Therefore, how to improve the application rate and daily maintenance of satellite receiving antenna has become one of the most important research topics.
