Abstract
A communications antenna is disclosed having improved mechanical strength, gain and reduced lateral dimensions. The antenna includes a three quarter wave length vertically disposed elongated radiating element and a plurality of one-quarter wave length diverging elements connected at their bottom end to the bottom of the vertical radiator. The diverging elements flare upwardly and outwardly from the radiator at an acute angle, typically between about five degrees and about thirty degrees. The band width of the antenna may be broadened by interconnecting the free ends of the diverging elements such as by a conductive hoop.
