摘　　要：正规的电视调频发射天线的服务范围都是以天线杆为中心的近似圆型复盖面。但由于地理位置或是其它条件的限制，不能完全满足要求。本文提出了一个发射功率有效地定向复盖非圆型服务区的设计与制造电视与调频天线的简易方法，经过多年运行，实践证明是十分可靠的。Normal transmitting antenna of TV and modulating frequency has a servicerange which covers an area closely resembling a circle with the antenna as its centre. How-ever,due to the restrictions of geographical positions or other conditions,a non-circularcoverage is needed.This article presents a method of designing and manufacturing a TVand modulating frequency antenna with a transmitting power that effectively covers anon-circular service area. After several years of operational practice,it has been provedthat the method is completely reliable.
