传统的中波发射天线是一种实用的但原始的天线,由于占地面积巨大,它一直制约着中波广播事业的发展。新型的双锥中波小天线无须地网,可以架设在服务区内甚至屋顶上,它的覆盖效果与传统的铁塔天线相当。本文简要介绍了双锥中波小天线的开发思路和结构原理。双锥小天线适合于50Kw以下的中小功率发射台,它对无人值守的小功率、灵活覆盖和未来的DRM应用都将做出积极的贡献。
The traditional medium wave transmitting antenna is a practical but primitive antenna that has always restricted the development of the medium wave broadcasting business because of its huge area. The new double-cone small wave neutral antenna without network, can be erected in the service area and even on the roof, its coverage effect and the traditional tower antenna quite. This article briefly introduces the development idea and structure principle of double cone mid-wave small antenna. Biconical small antenna is suitable for small and medium-power launch pad below 50KW, it will make a positive contribution to unmanned low power, flexible coverage and future DRM applications.
