Abstract: Filter arrangement comprising an inner electric conductor comprising at least one inner conductor segment, an outer electric conductor at least partly surrounding the inner conductor, at least one dielectric element and at least one coil spring. The at least one dielectric element is arranged sandwiched between at least one inner conductor segment and the outer conductor to form a capacitance between the outer conductor and the inner conductor segment. The at least one coil spring is arranged inside said outer conductor to force the inner conductor segment and the at least one dielectric element against the outer conductor. The at least one coil spring is made from an electrically conducting material to form an inductance and is electrically connected with the inner conductor segment. An antenna feeding network and a multi-radiator antenna comprising such a filter arrangement is also provided.

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.
