摘要
本文介绍了五六六台200kW双频共塔并馈中波天线从天线选型到天线施工设计的过程。针对天线底部高电压及大电流,设计出满足要求的馈电网络。经过工程测试,天线系统指标良好,场强覆盖范围达到了预定的目标。
This paper introduces a 200kW duplex on shunt-fed medium antenna in Station 566 including the whole process from selecting antenna to antenna construction design. Aiming at high voltage and large current at the bottom of the antenna, a feed network is designed to meet the requirements. By engineering test, the antenna system is verified to be good. The field strength coverage reaches a predetermined target.
