Abstract
The invention relates to a manual actuating device for a phase shifter of a base station antenna. The device includes a support module having an elongated base body and a first and a second receiving portion which protrude from the base body and are spaced apart in a longitudinal direction of the base body; and a lead screw drive having a lead screw and a nut. The lead screw is rotatably supported in the first and the second receiving portion, and the nut is translationally movably installed on the lead screw. The device also includes an actuator rod connected to the nut and configured to actuate the phase shifter; and a manual operating part connected with the lead screw and configured to manually operate the lead screw to rotate the lead screw. The actuating device is simple and compact in structure and is easy to manufacture and install.
