Abstract
The invention relates to a summing member comprising in-connectors for receiving and combining different RF signals and an out-connector for supplying the combined signals further, at least one of the connectors being coaxial and comprising an elongated rod-like inner conductor, and an outer conductor surrounding the rod-like inner conductor. To provide an adjustable summing point, said at least one connector comprises a moveable part of low-loss dielectric material or ferrimagnetic material, the part surrounding at least the inner conductor and being moveable lengthwise of the inner conductor so as to adjust the phase angle of a wave reflecting from the connector.
