Abstract: The present invention relates to an end cover assembly for a base station antenna, comprising: an end cover (3) having a bottom plate, wherein the bottom plate has a through hole (7); an electrical connector (4) having a flange (10), wherein the electrical connector is configured to be received in the through hole. The geometry of the through hole and the geometry of the flange are configured such that the flange can be inserted from an exterior of the end cover and through the through hole, and the flange is capable of abutting against an inner surface of the bottom plate adjacent an inner edge of the through hole inside the end cover, wherein the flange is securable to the bottom plate at a predetermined position of the flange relative to the through hole when the flange abuts against the inner surface. The present invention further relates to a base station antenna comprising the end cover assembly, as well as an assembling method and a disassembling method for the end cover assembly. The risk of falling off of the electrical connector may be reduced, and the electrical connector can be removed more easily.

Abstract: A radome for a base station antenna comprises a cover and a bracket. The cover spans over radiators of the base station antenna. The cover includes a front wall, first and second side walls that extend rearwardly from the front wall, and first and second rear flanges that extend inwardly from the respective first and second side walls. The bracket includes a body and first and second mounting flanges that extend forwardly from the body. The first and second mounting flanges cooperate with the respective first and second rear flanges of the cover to connect the cover to the bracket. The radome has an aesthetic appearance, and reduces the possibility that a screw is loosened as a result of lateral wind forces.
