Abstract
A diagnostic method for monitoring at least one plug-in connection (4) to an antenna (1), a diagnostic signal is supplied via the antenna signal path toward the antenna (1). The diagnosis signal bypasses an active circuit (31) in the antenna signal path. In the event of a defective plug-in connection (4), the diagnostic signal influences the power supply of the active circuit (31). If the power consumption is outside a predefined window, an error is signaled.

11. A diagnostic method for monitoring at least one plug-in connection to an antenna, the plug-in connection being in an antenna signal path to the antenna, comprising:
-
supplying a diagnostic signal via the antenna signal path toward the antenna (1), the diagnostic signal bypassing an active circuit (31) provided in the antenna signal path, influencing a power supply of the active circuit (31) depending on whether the diagnostic signal is affected by an error due to the at least one plug-in connection (4), and detecting whether power consumption of the active circuit (31) is outside a predefined window, and if so signaling an error. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A diagnostic device for monitoring at least one plug-in connection to a window-integrated antenna of a vehicle, the plug-in connection being in an antenna signal path to the antenna, the device comprising:
-
means for generating a diagnostic signal and for feeding this signal into the antenna signal path toward the antenna (1), means for enabling the diagnostic signal to bypass an active circuit (31) in the antenna signal path (31), means for influencing the power supply of the active circuit (31) depending on whether the diagnostic signal is affected by an error due to at least one plug-in connection (4), and means for detecting power consumption of the active circuit (31) and for signaling an error if the power consumption is outside a predefined window. - View Dependent Claims (25, 26, 27, 28, 29)
