摘　　要：中短波天馈线系统具有无线电信号传输距离较远、信号覆盖广泛、信号接收容易等优势,但是也存在抢修难度较大、故障率较高等不足,一旦出现故障,将会对发射工作以及安全传输产生较大影响。基于此,文章针对中短波天馈线系统的维护及常见故障处理技术进行研究,以期为中短波天馈线系统的有效维护提供有价值的参考依据。The medium and short wave antenna feeder system has the advantages of long radio signal transmission distance, wide signal coverage and easy signal reception, but it also has the disadvantages of difficult emergency repair and high failure rate. Once a failure occurs, it will have a great impact on the transmission work and safe transmission. Based on this, this paper will study the maintenance and common fault handling technology of the medium and short wave antenna feeder system, hoping to provide a valuable reference for the effective maintenance of the medium and short wave antenna feeder system.
