Abstract
A vertical grounded antenna is supplied at one third of its height. The antenna is substantially a whole wave antenna and, in order to reduce the secondary lobes of the vertical pattern of said antenna, its height is so determined as to produce an inversion of the sign of the phase of the current on each side of the feed input.
