A bipolar lightning rod apparatus includes a fixation plate, a rod member configured to have one end connected to the fixation plate in a length direction thereof and charged with the electric charges of a ground, at least two insulators installed in the length direction, an electrification plate installed between adjacent insulators, electrically insulated from the rod member, and charged with electric charges having an opposite polarity to the electric charges of the ground, an electrification tube installed between the electrification plate and the insulators, electrically connected to the electrification plate, and charged with electric charges having an opposite polarity to the electric charges of the ground, and a rod cap connected to the top of the rod member and configured to induce the falling of a thunderbolt. The rod cap has an outside diameter greater than that of the insulators. |
