摘要
为解决传统中波发射天线的拉线,地网占地大问题,采用了锥面顶负荷中波小型发射天线,其高度为λ/13,占地面积21m2,地网半径7m,846kHz与1521kHz共塔运行。天调匹配方便快捷,2005年7月6日统调成功工作至今,天馈线系统运行正常,发射机工作稳定。
In order to solve problems that the guy and grounding grid traditional MW antenna needs cover largearea,in recent years,several new types of small-size MW antennas have come out,and get the industry'sattention. Characteristic,principle,structure and prospects of a small-size MW antenna with cone top load are expoundedin the essay as a reference for everyone.
