1. A base station antenna, comprising:
a remote electronic tilt (“RET”) actuator;
a first mechanical linkage connected between the RET actuator and a first phase shifter, and a second mechanical linkage connected between the RET actuator and a second phase shifter, wherein the RET actuator comprises:
a rotary drive element movable in a first rotary direction and a second rotary direction;
a first drive system connected between the rotary drive element and the first mechanical linkage, the first drive system moving the first mechanical linkage in a first linear direction and a second linear direction when the rotary drive element is moved in the first rotary direction; and
a second drive system connected between the rotary drive element and the second mechanical linkage, the second drive system moving the second mechanical linkage in a third linear direction and a fourth linear direction when the rotary drive element is moved in the second rotary direction.
