Bushing for an electrical high-frequency signal and with such an implementation Füllstandmeßeinrichtung

The invention relates to a system for testing an electric high frequency signal, comprising at least one conductor element (6) wherein the electric high frequency signal is fed thereto at an input point (10) and transmitted at an output point (17) to a probe (7) which is used to guide the high frequency signal. The invention also comprises a single or multi-part mechanical support element (1), and a single or multi-part insulation (11,12) which is arranged between the support element (1) and the conductor element (6). The inventive system is characterised in that the impedance of said system and the impedance of the probe (7) connected to the output point (17) are substantially equalised at said output point (17).
