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.
