为解决传统中波发射拉线天线、地网占地面积大,用地紧张的矛盾,河南省2008年试探性的在潢川中波台发射747KHz(25KW)农村广播时,采用陕西广通电子科技有限公司生产的33m抛物面中波小天线,通过三年来的调试与不断改进,运行良好,与传统天线相比,具有占地面积小、安装方便灵活、天调匹配简捷、易于维护保养等优点,为用地紧张的中波发射台(站)提供一种选择。本文仅就中波小天线技术特点、安装方法、使用中出现的问题及改进方法做初步探讨。
In order to solve the contradiction between traditional medium wave launch antenna and large area network and land shortage, when Henan Province tentatively launched 747KHz (25KW) rural radio broadcast in Huangchuan Medium Wave Platform in 2008, Shaanxi Guangtong Electronic Technology Co., Ltd. Production of 33m parabolic wave small antenna, through three years of debugging and continuous improvement, running well, compared with the traditional antenna, with a small footprint, easy and flexible installation, simple matching, easy to maintain and so on, for the use of land Nervous medium wave launch pad (station) to provide an option. This article only on the small wave antenna technology features, installation methods, the use of the problems and improve the method to do a preliminary discussion.
