Multi-RET actuators include a plurality of shafts that have respective axially-drivable members mounted thereon. Each of axially-drivable member is mechanically linked to a respective one of a plurality of phase shifters. The multi-RET actuator further includes a motor having a drive shaft and a gear system that is configured to selectively couple the motor to the respective shafts. The gear system is configured so that rotation of the drive shaft in a first direction creates a mechanical linkage between the motor and a first of the shafts 1340/1342, and rotation of the drive shaft in a second direction that is opposite the first direction rotates the first of the shafts.

A mechanical tilt mounting system for a base station antenna includes a fixed pivot that connects the antenna to a support structure. The antenna is rotatable about the fixed pivot. An adjustable control arm has a first end connected to the antenna and a second end connected to the support structure. Extension and contraction of the adjustable arm rotates the antenna about the fixed pivot to change the angle of inclination of the antenna.

A base station antenna device includes an antenna module having a separation space spaced a predetermined distance forward from a support pole, a remote radio head (RRH) provided on the rear surface of the antenna module such that the RRH is slidably assembled in a detachable manner in a horizontal direction from a lateral side of the separation space, and an adapter having a push block provided on a lower end portion of the RRH so as to mediate the electrical signal connection and disconnection between the antenna module and the RRH by means of a pushing operation in the longitudinal direction.

In one embodiment, an antenna assembly is described. The antenna assembly includes and antenna and an antenna positioner coupled to the antenna. The antenna positioner includes a single drive interface and a plurality of gears. The plurality of gears rotate in a first manner in response to a first drive direction applied through the single drive interface, and rotate in a second manner in response to a second drive applied through the single drive interface.
