Abstract: An antenna feeding network for a multi radiator antenna is provided. The antenna feeding network comprises at least one coaxial line. Each coaxial line comprises a central inner conductor and an elongated outer conductor surrounding the central inner conductor, wherein at least one of the outer conductors of the coaxial lines is provided with an opening, wherein the antenna feeding network further comprises at least one nonconductive holding element configured to be placed in the opening. The holding element is configured to hold at least one of the inner conductors in position. The invention further relates to a multi radiator antenna comprising such an antenna feeding network, and to a method for providing an electrical connection in such an antenna feeding network.

Abstract: An antenna feeding network for a multi-radiator base station antenna and an antenna arrangement comprising such a feeding network is provided. The feeding network comprises substantially air filled coaxial lines and a coaxial connector for an antenna feeder cable, the connector being connected to at least one of the coaxial lines. The substantially air filled coaxial lines each have a central inner conductor and an elongated outer conductor surrounding the central inner conductor. The coaxial connector comprises a body having an attachment portion, the attachment portion being attached to, and arranged in abutment with, a portion of at least one outer conductor such that the body connects electrically and mechanically with the outer conductors of the coaxial lines.
