Abstract: The present invention relates to a sealing member for a base station antenna and a base station antenna comprising the same as well as a method and device for manufacturing the sealing member. The sealing member (2) is flexible and resilient and is configured to form a seal between an open end (5) of a radome (3) and an end cap (1) of the base station antenna. The sealing member is an elongated sealing strip having two ends, wherein the two ends of the sealing member are lappable with each other, and the sealing member has a groove extending over its entire length, which groove is defined by two side limbs and a bottom limb connecting the two side limbs of the sealing member, wherein the groove is configured to engage with an edge of the open end (5) of the radome, and wherein the sealing member is configured to be received in an annular recess of the end cap (1) and isolate an interior of the radome (3) from the environment. The sealing member can be manufactured cheaply and can be flexibly applied to base station antennas with different sizes.

Abstract: Base station antennas include a reflector, a first array of cross-polarized radiating elements that are mounted to extend forwardly from the reflector, and a parasitic assembly. The parasitic assembly includes a base that is mounted on the reflector, a horizontal component shaping element, and a forwardly projecting member that projects forwardly from the base that is coupled between the base and the horizontal component shaping element. The horizontal component shaping element may extend substantially parallel to a plane defined by the reflector and may include a proximate side that is directly connected to the forwardly projecting member and a distal side that is opposite the proximate side. The distal side of is only electrically connected to the reflector through the proximate side.
