An end cover includes an end cover plane perpendicular to a longitudinal axis of a radome and passes through a connection part of the end cover and the radome. Outlines of a cross section of the end cover includes a first spline curve between a first end point and a first intermediate point having at least one first curvature, and a second spline curve between a second intermediate point and a third intermediate point having at least one second curvature. The first intermediate point and the second intermediate point are not in the end cover plane. A distance between the first intermediate point and the end cover plane and a distance between the second intermediate point and the end cover plane are equal and not less than a distance between any point on the cross section of the end cover and the end cover plane.

A phase shifter assembly includes: a first phase shifter including a first through-hole; a second phase shifter including a second through-hole and disposed at a side of the first phase shifter; a first gear including a third through-hole and disposed at a side of the second phase shifter facing away from the first phase shifter; a rack configured to drive, through driving the first gear, the second phase shifter to move relative to the first phase shifter, to adjust an electrical tilt angle of an antenna corresponding to the phase shifter assembly; and a first reversing mechanism disposed between the first gear and the rack and engaged with the first gear and the rack, respectively, making a direction of a component of a linear velocity at an electrical contact between the first phase shifter and the second phase shifter in a moving direction of the rack is opposite to the moving direction of the rack.
