Does an attic TV antenna need to be grounded?

Does an attic TV antenna need to be grounded?

TV antennas in the attic do not require grounding. However, because the coax cable will run on the exterior of the house I recommend that the coax cable be grounded at the location near to where it re-enters your home. The signal splitter becomes the ground block and grounds the coax cable.

How do you ground an antenna cable?

How to Ground a TV Antenna Coax

1. Find a Spot to Install the Grounding Block or Lightning Arrester.
2. Attach the Block to the Wall.
3. Run the Antenna Cable to the Block and Attach It.
4. Run Another Coaxial Cable from the Block to Your TV or Set-Top Box.
5. Attach a Grounding Wire to Both the Block and House Ground Wire.

How do you ground an attic antenna?

If it needs grounding it can’t go in the attic, because code requires that grounded antennae be on the edge of the roof and that the wire from the antenna to the ground follow a straight line path (or something like that – I’m not the electrician).
