The present invention relates to base station antennas having remote electronic tilt capabilities. Actuators for multiple phase shifters are described herein. An actuator may include a motor, a linkage drive system including a plurality of drive mechanisms for driving mechanical linkages of multiple phase shifters, a linkage selection system that is configured to selectively connect the motor to a selected one of the drive mechanisms of the linkage drive system. The linkage selection system may include a support seat, a carrier disposed on the support seat, and a movement transmission mechanism.
