The present invention provides a method for controllably moving a plurality of antennae in a wireless communications system. The method comprises activating a first and second actuator associated with a first and second one of the plurality of antennae to move the first and second antennae to a desired position. The power delivered to the first and second actuators is measured, and at least one parameter of at least one of the first and second actuators is reduced in response to the measured power being greater than a setpoint.
