A mobile radio antenna comprises a multi beam forming device which comprises a drivable drive element having a drive shaft and at least two output shafts. Each output shaft is substantially parallel to the drive shaft. At least one output gear is rotationally fixed to the output shaft. At least two phase shifters are each operatively connected to a respective output shaft via a respective drive device. A changeover device enables the drive element to be operatively connected selectively to at least one of the output gears.

A flexible shaft for torque transfer has a plurality of metal wires that are helically wound in a plurality of layers with an opposite winding direction that alternates from layer to layer. Each of the metal wires is surrounded by an electrically insulating insulation layer. The insulating layer prevents a metal-on-metal contact between adjacent metal wires and thereby prevents unwanted intermodulation products.

A multi-beam-shaping structure is distinguished by the following features: the multi-beam-shaping structure is provided with at least one electronic communication interface for controlling the multi-beam-shaping structure for setting the at least two radiation diagrams differently, the multi-beam-shaping structure comprises at least one driver, preferably comprising an electric motor, and preferably a power unit, the multi-beam-shaping structure comprises at least two first mechanical interfaces and/or coupling points, a drive connection engages on each of the at least two first mechanical interfaces and/or coupling points, the at least one driver of the multi-beam-shaping structure is connected to the at least two mechanical interfaces and/or coupling points via a multidrive, it being possible to actuate selectively at least one of the plurality of drive connections in each case via the at least one driver and the associated controller, and the number of interfaces and/or coupling points being greater than the number of driver.

A coaxial HF plug-in connector comprises an axial bore embodied in an external conductor material on a connection side, in which an electric component is arranged. The aim is to improve the connector. For this purpose, the component in the axial bore is embodied in the form of an output branch which comprises a lower NF conductor, an internal dielectric, a balun and an external dielectric. The lower NF conductor is electrically connected to the balun base on the end of the in-plug connector connection side and to the internal conductor of the plug-in connector on the open end of the balun.

The invention relates to an electrical terminal connection, especially for connecting an outer conductor of a coaxial cable, characterized by the following novel developments: the electrical terminal connection is embodied in a two-stage manner; the plug-in element comprises at least two plug-in sections which are staggered in the plug-in and axial direction, both the first plug-in section in the plug-in direction and the following plug-in section being provided with a knurl on the outer periphery thereof; the receiving opening comprises a first receiving section and a second receiving section which are staggered in the plug-in and axial direction of the plug-in element; and the cross-sectional size of the two plug-in sections and the two complementary receiving sections differs in that the radial dimension or outer dimension of the plug-in sections provided with the knurl is slightly larger than the radial or outer dimension of the receiving section respectively co-operating therewith.
