随着无线和卫星技术的发展,卫星电视由传统的模拟信号改变为现代的数字信号,而接收方式也较以往发生了巨大的变化,加上部分地区各类阻波器的使用,大大地干扰着数字电视卫星接收天线的使用效果。因此,需要对数字电视卫星接收天线进行特殊的制作与改良,本文通过对数字电视卫星接收天线的组成、原理以及当前的问题进行了分析和研究,并提出了改进天线效果的措施,仅供参考。
With the development of wireless and satellite technologies, the satellite television has changed from a traditional analog signal to a modern digital signal, and the receiving method has also undergone tremendous changes than before. Coupled with the use of various types of wave blockers in some areas, it greatly interferes with The use of digital TV satellite receiving antenna effect. Therefore, it is necessary to specially make and improve the digital TV satellite receiving antenna. In this paper, the composition, principle and current problems of digital TV satellite receiving antenna are analyzed and studied, and the measures to improve the effect of the antenna are proposed for reference only .
