The present invention relates to a system for the wireless coupling of a cellular radio end device to at least one first external antenna, in particular for coupling to an external vehicle antenna, having a coupling structure for the wireless coupling to an antenna structure of the cellular radio end device, wherein the coupling structure has at least two connections; and having a connection unit that connects the first external antenna to one of the at least two connections of the coupling structure in dependence on the coupling quality, wherein the connection unit evaluates the coupling quality between the antenna structure of the cellular radio end device and the at least two connections of the coupling structure during the normal communication operation of the cellular radio end device and/or continuously and/or for both connections simultaneously.

System for the wireless coupling of a cellular radio end device to an external antenna structure

The present invention relates to a compensator for the compensation of line losses and/or coupling losses on the connection of a cellular radio end device to an external antenna structure, in particular to an external vehicle antenna structure, wherein the compensator has a first signal path for connecting the cellular radio end device to a first external antenna of the external antenna structure, with the compensator having a second signal path for connecting the cellular radio end device to a second external antenna of the external antenna structure.

Compensator

An improved rooftop antenna is characterized, inter alia, by the following features: the base () has a protruding base foot part () on the base lower side () of said base; the base foot part () is formed integrally with the remaining part of the base () or connected thereto and is electrically conductive or coated, together with the base (), with an electrically conductive layer; the base foot part () has a channel (), which passes through the foot part () transversely and preferably perpendicular to the base () in a plug-in and joining direction (Z) for accommodating the at least one coaxial line (); and the coaxial line () is inserted into the at least one channel () of the base foot part () in such a way that at least one section of the outer circumference of the outer conductor () of the coaxial line () is pressed mechanically with the electrically conductive inner wall of the channel () of the base foot part () and DC contact is thereby made therewith.
