低频低塔环境下中波共塔技术应用

Application of MW Sharing-tower Technology in Low-frequency and Lowtower

本文对山西省忻州中波台三频分馈共塔网络的实现进行了介绍,针对540kHz频率在76米拉线塔上,天调网络在单频工作状态也有可能不太稳定的情况下,通过设计天调网络来满足运行要求,实现了低频低塔三频共塔播出。

The paper introduces the realization of the tri-band common tower networks of the medium wave station in Xinzhou, Shanxi. With a frequency of 540kHz and 76-metre guyed tower, the single band working condition of antenna tuning network is possibly less stable. By adjusting the designs so as to fulfi ll the operational requirements, the broadcast of tri-band common tower is achieved with low-frequency on low towers.
