This page describes the proper method for grounding an outdoor TV antenna based upon the National Electrical Code (NEC) and NFPA 70. Outdoor TV antennas can build-up static electricity as a result of simply being outdoors. This static electricity can attract lighting during a thunderstorm. As a result, it is essential that all outdoor TV antennas AND the coax cable are properly grounded. Grounding both the antenna mast and the grounding of the coax cable will route the lighting into the GROUND and not into your house. The following describes the parts required along with the proper method for grounding the antenna mast and the coax cable.
Parts Required to Ground the TV Mast and Ground the Coax Cable
1. Ground Clamp for the TV Antenna Mast
Depending on the size of the antenna mast you have, you will need one of the two ground clamps shown below. The first clamp will fit an antenna mast that is between 1/2 inch to 1 inch diameter. The second ground clamp will fit an antenna mast that is 1 1/4 inch to 2 inch diameter.
