Lightning rods do not attract lightning, but if lightning strikes the rod or very near the rod, it will choose to take the path of least resistance. That is why a single lightning rod may be inadequate for good protection.
Modern Lightning Rods
Lightning rods are not a thing of the past, and there are many installed on homes across the country. In fact, proper lightning protection systems have multiple lightning rods spread out across the top of the structure. You don’t see them because they aren’t the tall monstrosities that they once were. Most people won’t notice or recognize them because they are very inconspicuous.
