摘要
中波天馈线匹配网络的作用是实现天线与馈线的匹配,从而降低反射功率,提高发射系统的工作效率.由于土地资源日益紧张,中波发射台没有额外的空间来增加天线数量,而广播节目数量和发射功率在持续增长.为了应对这一挑战,中波发射台普遍采用双频共塔或三频共塔的方式来满足播出需求.基于此,结合饶平中波转播台双频共塔设计、安装及调试方面的实践经验,详细论述中波双频同塔的设计原则及安装调试的具体方法.
Abstract
The function of medium wave antenna feeder matching network is to realize the matching of antenna and feeder,so as to reduce the reflection power and improve the efficiency of the transmitting system.Due to increasingly tight land resources,there is no additional space to increase the number of antennas on the medium wave transmitting station,while the number of broadcast programs and transmission power continue to grow.In order to deal with this challenge,the medium wave transmitting station generally adopts the way of dual-frequency common tower or triple-frequency common tower to meet the broadcast demand.Based on this,combined with the practical experience in the design,installation and commissioning of the double-frequency common tower of Raoping medium wave broadcasting station,the design principle and the concrete method of installation and commissioning of the double-frequency common tower are discussed in detail.
