Abstract: A reflector for a multi-radiator antenna which comprises electrically conducting reflector parts and one or more connector device. At least two reflector parts are each provided with at least one connecting portion. At least one connector device is adapted to provide an electrical interconnection between at least two of the reflector parts. At least one connector device comprises a metallic film and one or more holding elements. The metallic film is adapted to be arranged in abutment with connecting portions of the at least two of the reflector parts to achieve the electrical interconnection. At least one of the holding elements has at least one holding portion adapted to connect to a connecting portion of a reflector part with said metallic film sandwiched therebetween.

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: The invention relates to a system for the supervising of a receiving antenna, the system comprising partly a first sensor for the sensing of an incoming electrical signal from the receiving antenna to the first sensor, a signal processing circuit with an interface, the first sensor being permanently connected between the receiving antenna and receiving circuits and the sensing being carried out at any moment without changing the mutual connection configuration of the receiving antenna and the receiving circuits. The system is provided with a test transmitter connected to the receiving antenna via a coupling circuit and in front of a second sensor, which is permanently connected between the receiving antenna and the receiving circuits, the second sensor being arranged for the sensing of an outgoing electrical signal to the receiving antenna and the signal processing circuit being arranged to deliver, via the interface, an indication of the operability of the receiving antenna based on the sensing.
