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: 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.

Abstract: The invention relates to a cable sealing device comprising: a first plate having a group of first holes and configured to be mounted to a first side of a housing wall; a second plate having a group of second holes and configured to be mounted to a second side of a housing wall; and a soft elastic sealing element configured to be mounted between one of the first and second plates and the housing wall. The group of first holes and the group of second holes and the sealing element are configured to receive a group of cables, and the first and the second plate can be biased toward each other, so that the sealing element can be pressed and elastically deformed. The sealing element can seal and fix the group of cables in the housing wall in a pressed and elastically deformed status. The invention also relates to a cable sealing system comprising a housing wall and the cable sealing device. The cable sealing device is simple in structure and easy to assemble, and can ensure good sealing and fixing of the cables.

Abstract: Base station antennas comprise a planar reflector, a radiating element mounted to extend forwardly from the planar reflector, the radiating element including a dipole that comprises an inner dipole arm and an outer dipole arm, and a radome having a front wall, a side wall and a curved front transition wall that connects the front wall to the side wall. A distal end of the outer dipole arm is closer to the planar reflector than is a base of the outer dipole arm, and an overlap portion of the outer dipole arm overlaps the curved front transition wall. A largest minimum distance between any point on a front surface of the overlap portion of the outer dipole arm and the radome is less than twice a smallest minimum distance between any point on the front surface of the overlap portion of the outer dipole arm and the radome.
