Code Q&A

Q. I’ve been looking online, but I can’t seem to find a consistent answer on whether a television antenna placed in the attic needs to be grounded. Does it?

A. No. Each lead-in conductor from an outdoor antenna must be provided with a listed antenna discharge unit or a ground block if the cable has a shield-like coaxial cable [810.20(A)]. Antennas located indoors (like in an attic) aren’t required to have an antenna discharge unit. Therefore, they aren’t required to be grounded.
