短波发射天馈线系统是短波中一个重要的组成部分。天线是把馈线里需要传输的电磁波加以转换,转换后的电磁波可以在自由的空间进行传播。馈线即传输电磁波的通道。就短波发射天馈线系统来讲,它的技术性能与质量指标对短波的波道通信质量有直接的影响。通过对短波发射天馈线系统检验以后投入使用,需要加强其管理与维护。由于短波的发射天线,其种类众多,占地面积很大,造价也非常高,制作和安装过程较为复杂。所以,对短波发射短波发射天馈线系统的维护工作要求极高。
Shortwave transmitting antenna feeder system is an important part of the shortwave. Antenna is to feed the need to transmit electromagnetic waves to be converted, the converted electromagnetic wave can be transmitted in free space. Feeder that is the transmission of electromagnetic waves channel. In terms of shortwave transmitting antenna feeder system, its technical performance and quality indicators have a direct impact on the shortwave channel communication quality. Through the launch of shortwave transmitting feeder system test put into use, need to strengthen its management and maintenance. Due to the shortwave transmitting antenna, its variety, covers a large area, the cost is also very high, the production and installation process is more complicated. Therefore, the shortwave transmitting shortwave antenna feeder system maintenance requirements are extremely high.
