Base station antennas with low-band arrays having low-band radiating elements having parasitic monopole elements

A base station antenna, comprising:

• a reflector:
• a first plurality of cross-dipole radiating elements that are arranged as a first array of cross-dipole radiating elements, each cross-dipole radiating element comprising a first dipole radiator having a first dipole arm and a second dipole arm and a second dipole radiator having a third dipole arm and a fourth dipole arm;
• and
• a plurality of parasitic monopole elements that are associated with a first of the cross-dipole radiating elements, each parasitic monopole element including a monopole radiator, wherein each monopole radiator is positioned at least partly within a footprint of the first and second dipole radiators of the first of the cross-dipole radiating elements when the first of the cross-dipole radiating elements is viewed from the front, and
• wherein at least some of the monopole radiators extend forwardly from the reflector at an angle of between 10° and 80°.
