中波广播发射天线的原理与维护

Principle and Maintenance of Medium Wave Broadcast Transmitting Antenna

中波发射发射天线是广播电台重要的基础设施建设,也是其全面履行职责的重要保障,作为传输的重要部件,中波发射发射天线的传输质量往往是广播电视台特别关注的问题,中波广播传输主要靠电波操作,白天以地波的形式广播,夜间以地波和天波的形式同时广播,借助发射天线传输中波广播,传输中波广播早已在我国得到广泛应用,它是我国无线电广播中覆盖面积较大的一种节目播放方式。本文以中波广播发射天线原理的基本原理为基础,从讨论中波广播发射天线的发射原理出发,讨论其发射的基本原理,并就此讨论其维护对策,保障电视广播发射塔正常运行。

Medium wave transmitting antenna is not only an important infrastructure construction of radio stations,but also an important guarantee for t heir full performance of their duties.As an important part of transmission,the transmission qualiiy of medium wave transmitting antenna is often a special concern of radio and television stations.Medium wave broadcasting transmission mainly depends on radio wave operation.Broadcast in the form of ground wave during the day and simultaneously in the form of ground wave and sky wave at night.Medium wave broadcasting has been widely used in China with the help of transmitting antenna.It is a program broadcasting mode with large coverage in China's radio broadcasting.Based on the basic principle of medium wave broadcast transmitting antenna,starting from the discussion of the transmitting principle of medium wave broadcast transmitting antenna,this paper discusses the basic principle of its transmission,and discusses its maintenance countermeasures to ensure the normal operation of TV broadcast transmitting tower.
