A horizontally polarized antenna may be mounted or operated with a vertical axis of the antenna being substantially perpendicular to a plane defined by the surface of the earth, and still emanate an electric field that is parallel to the surface of the earth. Use of horizontal polarization may improve communications reliability by reducing interference from predominantly vertically polarized signals in overlapping and adjacent frequency bands. Also, a vertically polarized antenna may be mounted or operated with a vertical axis of the antenna being substantially vertical to a plane defined by the surface of the earth, and still emanate an electric field that is vertical to the surface of the earth. A horizontally polarized antenna and a vertically polarized antenna mounted with their vertical axes collinearly aligned, but both antennae physically separated, provide a compact dual polarized unit emanating vertical and horizontal polarized electric fields.
