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 feeding 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 feeding 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 feeding lines.

Abstract: A multi radiator antenna comprising an electrically conductive reflector, at least two radiating elements arranged on said reflector, a feeding network connected to the radiating elements, and a protective cover. The feeding network comprises a plurality of conductors for distributing signals to the radiators. The feeding network has means for adjusting relative phases of said signals in order to adjust a direction of the antenna main lobe of said multi-radiator base station antenna. The means for adjusting is provided with, or is connected to, an indicating portion configured to provide a visual indication of said direction. The protective cover is provided with an at least partially transparent wall portion arranged such that said indicating portion is visible there through.
