A base station antenna includes: a plurality of reflector panels; a plurality of printed circuit boards (PCBs), each of the circuit boards mounted on a respective one of the reflector panels; a plurality of radiating elements mounted on each of the PCBs, wherein the PCBs and the radiating elements are configured and arranged so that the base station antenna receives and transmits radio frequency signals in a first frequency band and a second frequency band; first and second wiper members pivotally mounted on each PCB at respective first and second pivots, the first and second wiper members being configured such that pivotal movement of the first and second wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in first frequency band; third and fourth wiper members pivotally mounted on each PCB at respective third and fourth pivots, the third and fourth wiper members being configured such that pivotal movement of the third and fourth wiper members induce downtilt angle adjustment in the radiating elements that transmit and receive signals in a second frequency band; and a phase shifter linkage comprising a first carrier member and a second carrier member fixed relative to the first carrier member, the first carrier member engaging the first and second wiper members and the second carrier member engaging the third and fourth wiper members. Actuation of the phase shifter linkage causes the first carrier member and the second carrier member to move in concert relative to the PCBs, so that downtilt angle adjustment of the first frequency band equals downtilt adjustment of the second frequency band.
