Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The lightning rod requires a connection to earth to perform its protective function. In a lightning protection system, a lightning rod is a single component of the system. Lightning rods are also called finials, air terminals or strike termination devices.
If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution.
