Various kinds of Lightning arrester circuits are available, but here describes one with Multi-level protection so any one of the component may be damaged if a strong lightning occurs. Thus it leaves the gadget without damage. Usually one Surge protector like MOV, GDT, Bidirectional Diode etc is used in surge protector circuit. But here a combination of all the three is used to give multi level protection. The circuit can be hooked up in Telephones, Cable TV lines, Modem, Dish antenna cable etc.
