Abstract: A vertically oriented dipole antenna system for filling in overhead radiation or reception coverage with equidirectional-linear polarization (a linearly polarized field vector which lies in the plane of the system's vertical and horizontal axes) having, in combination, a balanced vertically oriented cylindrical dipole the inner adjacent ends of the elements of which are connected to supplemental conductors at points near the inner end of one element substantially ninety degrees apart along the circumference of the element and each extending outward a distance of the order of 0.15 of the wavelength of the mean frequency with which the antenna is to be operated and at an acute angle of the order of 33.degree.
