A base station antenna includes a first reflector structure that extends along a first longitudinal axis, the first reflector structure having a first transverse cross-section, a second reflector structure that extends along a second longitudinal axis, the second reflector structure having a second transverse cross-section that is different from the first transverse cross-section, and the second reflector structure extending above the first reflector structure, a first array of first frequency band radiating elements that are mounted to extend outwardly from the first reflector structure, a second array of second frequency band radiating elements that are mounted to extend outwardly from the second reflector structure, the first frequency band being non-overlapping with the second frequency band, and a radome that extends around the first reflector structure and the second reflector structure.
