Abstract
A high frequency signal feed through by which the ends of an input side coaxial cable and an output side coaxial cable, to be connected to each other, each comprising an interior conductor and an exterior conductor surrounding the interior conductor, are coupled to each other, showing a housing, a preferably pressure-resistant signal feed through arranged in the housing for the interior conductor, with the interior conductor being coupled at a conductive structure, arranged preferably centrally in the housing and capable of handling high frequencies, with at least one element for the galvanic separation being arranged between an input side and an output side, with the housing showing the structure for the galvanically separated coupling of the exterior conductor.
