Abstract: An assembly for a mobile communications antenna system includes a bracket assembly onto which an antenna array is mounted. The bracket assembly includes a steering arrangement configured to provide angular adjustment of an antenna beam azimuth, and an electromechanical tilting arrangement configured to adjust a tilt position of the antenna array. The steering arrangement and the electromechanical tilting arrangement are controllable in remote and manual operational modes to independently and variably adjust both azimuthal angle and tilt position of the antenna array. These operational modes ensure remote control of signal propagation and network coverage accuracy, and manual adjustment of the azimuth of the antenna beam and tilt position of the antenna array in case of field service or component failure.
