A radiating element for a base station antenna includes a feed stalk and a cross-dipole radiator mounted thereon. The cross-dipole radiator includes a dielectric mounting substrate, a first metal dipole that extends along a first axis on the dielectric mounting substrate, a second metal dipole that extends along a second axis on the dielectric mounting substrate that is generally perpendicular to the first axis, and an adhesive layer between the dielectric mounting substrate and the first and second metal dipoles.
