摘　　要：中波广播发射天线是无线广播领域的重要组成部分,主要通过天波或地波两种方式进行发射,具有稳定性好,覆盖区域广,成本低的优势。由于物理尺寸比较大,一般的中波发射天线都是由高塔组成,有单塔和多塔的形式。中波广播发射天线的维护工作也非常重要,从某种程度上说,中波天线维护的好坏直接影响到中波广播信号的覆盖效果。本文对中波广播发射天线的基本原理进行了阐述,对中波发射天线的维护要点进行了分析。可作为从事中波广播工作人员的入门参考。Medium wave radio transmitting antenna is an important part of wireless broadcasting field, and mainly transmits by sky wave or ground wave, which has the advantages of good stability, wide coverage area and low cost. Due to relatively large physical size, general medium wave transmitting antennas are composed of high towers, in the form of single tower and multiple towers. The maintenance of medium wave radio transmitting antenna is also very important. To some extent, the maintenance of medium wave antenna directly affects coverage effect of medium wave radio signal. This paper describes basic principles of medium wave radio transmitting antenna and analyzes main maintenance points of medium wave transmitting antenna. It can be used as an introductory reference for staff engaged in medium wave broadcasting.
