Radiator support, radiator and base station antenna

A multi-band base station antenna, comprising:

• an array of high-band radiators and an array of low-band radiators mounted to extend upwardly from a reflector plate,
• wherein at least one of the low band radiators is provided with a feeding stalk, a radiating element and a radiator support that includes a first support part and a second support part that are separate from each other, wherein the first support part extends for part of a height of the feeding stalk and bears radially the feeding stalk so as to prevent roll-over of the feeding stalk, and wherein the second support part is mounted adjacent a distal end of the feeding stalk away from the reflector plate, and receives the radiating element to thereby support the radiating element, and
• wherein a plurality of high-band radiators of the array of high-band radiators are provided adjacent a corresponding feeding stalk of one of the at least one low-band radiators.
