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 present disclosure relates to a support device for a phase shifter for a base station antenna. The support device includes a support plate suitable for fixation of a main printed circuit board of the phase shifter. The support plate includes a plate-shaped body and at least one support leg located at a lower portion of the body. At least one said support leg extends along a direction perpendicular to the body and is located on one side of the body, so that the support plate can be arranged in the base station antenna in a first orientation by at least one said support leg, or arranged in the base station antenna in a second orientation by the body itself according to layout requirements. The present disclosure also relates to an assembly for a phase shifter for a base station antenna and a method for soldering a coaxial cable to a phase shifter for a base station antenna.

Abstract: The present disclosure relates to an inclinometer for base station antennas, wherein the inclinometer is configured to be mounted to the base station antenna, and comprises: a movable weight configured to move to and stay at the force balance position in dependence on the mechanical tilt of the base station antenna under the action of gravity of the weight; an indicator coupled to the movement of the weight; and a plurality of graduations used in cooperation with the indicator for reading the mechanical tilt of the base station antenna. With the aid of this inclinometer, the mechanical tilt of the base station antenna can be easily and intuitively obtained.

Abstract: An actuator gearbox includes a drive shaft including a plurality of gear linkages that are spaced apart along the drive shaft, and a plurality of output shafts adjacent respective ones of the plurality of gear linkages. Each of the gear linkages includes a fixed gear coupled to one of the plurality of output shafts and a moving gear that is slideably coupled to the drive shaft. A bias spring is coupled to the moving gear to urge the moving gear out of engagement with the fixed gear. The mechanical switch moves the moving gear into engagement with the fixed gear on the output shaft adjacent the linkage to thereby cause the output shaft to rotate in response to rotation of the drive shaft.
