Abstract: The present disclosure relates to an antenna mounting device and a base station antenna system. The antenna mounting device includes a hinge device and an adjustment arm. The hinge device is configured to be mounted to a pole by a clamp and configured to pivotally connect a base station antenna arrangement. The adjustment arm is configured to be mounted to the pole by a clamp and configured to connect the base station antenna arrangement. The connection of the hinge device with the base station antenna arrangement is located in a middle region of a longitudinal extension of the base station antenna arrangement [having a longitudinal extension] of a maximum of ⅓ of the longitudinal extension of the base station antenna arrangement. A connection of the adjustment arm with the base station antenna arrangement is located in one of two end regions of the base station antenna arrangement. The adjustment arm has a plurality of connection positions for the corresponding clamp, which are configured to define a plurality of different mechanical tilt angles of the base station antenna arrangement about the hinge device. The antenna mounting device realizes easy adjustment of the mechanical tilt angle and good resistance against external disturbance loads.

Abstract: The present invention relates to a radiator support for a base station antenna. The radiator support includes a first support part and a second support part that are separate from each other. The first support part is configured to be mounted to extend upwardly from a reflector plate, to extend in part of a height of the feeding stalk, and to bear radially the feeding stalk so as to prevent roll-over of the feeding stalk. The second support part is configured to be mounted adjacent a distal end of the feeding stalk facing away from the reflector plate, and to receive a radiating element. The present invention also relates to a radiator having such radiator support, and a base station antenna having such a radiator. The radiator support according to the present invention has a simple structure, occupies a small structural space and has a favorable versatility.

Abstract: The present disclosure has disclosed a base station antenna comprising an antenna core provided with an antenna base at the bottom thereof and provided with an antenna bracket at the top thereof; and a radome sleeved over the antenna core. The radome includes a top wall and a side wall that protrudes downward from the top wall. The antenna core and the radome are connected together by a fixed connection portion located near a bottom end of the radome and a floating connection portion located near a top end of the radome. The floating connection portion fixes a position of the radome on the antenna core in a horizontal direction and allows the radome to float relative to the antenna core in a vertical direction by cooperating the antenna bracket with the top wall of the radome or the side wall at the top of the radome. The base station antenna solves the problem of a tensile force between the antenna core and the radome resulting from the temperature change, thereby improving the performance parameters such as PIM of the base station antenna.
