实践中可以看到,天馈线系统的稳定性会对广播电视信号传输的正常与否产生直接影响,因此,分析其原理及组成,做好日常维护与检修工作有着重要的现实意义。本文就针对该问题进行讨论,首先对天馈线系统的主要组成及工作原理进行分析,然后提出具体的维护措施。天馈线系统组成及原理天线与馈线系统,在广播电视发射和接收备设中,是不可缺少的重要组成部分。其中天线作为无线通信不可缺少的一部分,其基本功能是辐射和接收无线电波。发射时,把高频电流转换为电磁波,并以电磁波的形式向空间辐射出去。接收时,把一定方向的电磁波接收下来转换成
In practice, we can see that the stability of the antenna feeder system will have a direct impact on the normal transmission of radio and television signals. Therefore, it is of great practical significance to analyze its principle and composition, and to perform routine maintenance and overhaul work. This article addresses this issue, first of all the main components of the antenna feeder system and analysis of the working principle, and then put forward specific maintenance measures. Antenna system and the principle of feeders Antenna and feeder systems, radio and television transmitters and receivers in the establishment, is an indispensable part of the important. Antenna as an indispensable part of wireless communications, its basic function is to radiate and receive radio waves. Launch, the high-frequency current into electromagnetic waves, and in the form of electromagnetic radiation to the space radiation. Received, the electromagnetic waves in a certain direction to receive down into
