ABSTRACT:
A circuit arrangement for protecting electrical appliances such as radio and television sets from damage due to lightning during electrical storms, and the like. The antenna input and power supply lines are connected in a common circuit with one another and may further be connected to the chassis ground in response to movement of the usual on-off switch to the "off" position, thus eliminating any potential differences. This common circuit is isolated by a gap from all outside electrical sources when the set is turned off. Also, the antenna lead-in wires may be electrically connected to an outside, ground-driven rod when the set is turned off.
