摘　　要：中波广播在现代通信领域仍然占据着重要地位,尤其在偏远地区和夜间广播中发挥着不可替代的作用。中波发射天线以无线电波为基础,白天采用地波模式,夜晚采用地波与天波同步传输,具有覆盖面积大、发射容量大等特点。中波发射效果受到多种因素的影响,其中天线高度是一个关键因素。对此,探讨天线高度对中波发射效果的影响,并分析适配改造的技术方法及适配改造步骤,以期为中波广播的优化提供参考。Medium wave broadcasting still occupies an important position in the field of modern communication,especially in remote areas and night broadcasting plays an irreplaceable role.Based on radio waves,the medium wave transmitting antenna adopts ground wave mode during the day,and adopts ground wave and sky wave synchronous transmission at night.It has the characteristics of large coverage area and large transmitting capacity.The effect of medium wave transmission is affected by many factors,among which antenna height is a key factor.In this paper,the influence of antenna height on medium wave transmission effect is discussed,and the technical methods and steps of adaptation modification are analyzed,in order to provide reference for the optimization of medium wave broadcasting.
