1. A method of fabricating a radiating element for a base station antenna, the method comprising:
forming first through fourth metal dipole arms from one or more sheets of metal;
forming a dielectric mounting substrate via injection molding; and
mounting the first through fourth metal dipole arms to the dielectric mounting substrate via an attachment mechanism,
wherein each of the first through fourth metal dipole arms has spaced-apart first and second conductive segments that together form a generally oval shape, and
wherein each of the first and second conductive segments of the first through fourth metal dipole arms includes a first widened section that has a first average width, a second widened section that has a second average width and a narrowed section that has a third average width, the narrowed section being between the first widened section and the second widened section, wherein the third average width is less than half the first average width and less than half the second average width.
