SURGE PROTECTION DEVICE FOR COAXIAL CABLE WITH DIAGNOSTIC CAPABILITIES

摘要

A surge protection circuit (1) utilizing direct current (DC) voltage on the information carrying coaxial cable (18) of a receiving device with a surge protection device (10) to suppress transient signal fluctuations over the coaxial cable and a diagnostic surge protection status indicator (12) with on/off configurations to indicate the status of operation of the surge protection device (10). The visual indicator may be a light emitting diode or some other indicator device that when energized indicates normal operation of the surge protection circuit (1).
