• There really is only one way: it provides a path for the lightening so that you or your house is not the path. A lightening rod provides a path to ground in the event it is struck by lightening. A lightening rod is placed on the top of a structure (e.g., the peak of the roof of a house) and is grounded to earth. Lightening usually follows the shortest and easiest path - the lightening rod provides this path to ground, protecting people and structures from damage, injury, or death. The mast in a sailboat is a 'natural' lightening rod, but is not normally grounded. This makes it a potential safety hazard during a thunderstorm. Grounding can be provided by dropping a grounding wire into the water or, better, connecting to a metal surface on the outside of the hull (e.g., the keel).
