Abstract: An improved component for the separation or combination of high frequency outputs includes a coaxial input port located at the front end of the outer conductor. At the opposite end of the outer conductor, a head is located with at least two, and preferably three or four, single ports which cover the outer conductor connections. The head with the single ports is built as a single part to avoid any mechanical connection junctions. The head with the single ports which form integral outer conductor connectors consists of a forged part or a cast part.

A mechanical action axial stop on the connector or plug side of the plug connector is provided outside the high frequency signal path provided by the radial contacting device.

Abstract: An impedance converter device comprises an electrically conductive external conductor with one or more connection locations for electrical lines, an electrically conductive internal conductor with one or more connection locations for electrical lines, and also a dielectric arranged between external conductor and internal conductor. The external conductor comprises a base area bounded by one or more side walls thereby forming an external conductor housing with an internal space and an opening opposite the base area. The internal conductor is arranged in the internal space. The internal conductor and the external conductor are insulated from one another by the dielectric. The internal conductor comprises at least one cutoff bar-type section with a cutoff bar bottom and at least one wall which extends from the bottom in the direction of the opening of the external conductor housing.

Abstract: A broadband omnidirectional antenna includes an antenna element projecting from a base plate or counterweight surface. The antenna element has an outer surface which extends away from the base plate. The base plate has a recess in the area of which the foot point of the antenna element (which is in the form of a monopole) is arranged such that it is electrically conductively isolated from the base plate or from the counterweight surface. The antenna element is fed by means of a series or capacitive inner conductor line coupling.

Abstract: A multiband antenna has first and second antenna devices for transmitting or receiving. Each device has a dipole structure and associated dipole halves disposed opposite a base plate or reflector by baluns. The antenna devices are provided with a feed from a common antenna input line and a branch circuit. Frequency selective components are respectively associated with the first and second antenna devices. An electrical length of branch lines between a branch point and a feed point on the associated antenna devices having the dipole structure enables the frequency selective components respectively to reject a frequency band range transmitted via another of the first and second antenna devices.
