Grounding An Antenna In Attic

So there isn t any ground from the tv either to bleed off any voltage that might pass through the antenna.

Grounding an antenna in attic.

Exterior antennas must have their mounting rod grounded to provide electric discharge in the event of a lightning strike or static accumulation from other causes. Run a length of 6 jacketed stranded ground wire from whichever you installed there directly to your bussbar. But first check the electrical plugs of the various devices attached to the tv line. There are very specific requirements for grounding an antenna both via mast ground and a shield ground.

Stick to the building code. Air movement in your attic should not pose a problem. Try to keep your ground wire runs as short as possible and avoid making 90 degree turns or bends. Neither apply to an antenna in the attic.

You should therefore strongly consider grounding your attic mounted antenna by attaching a grounding block to the coaxial cable to shunt off excessive leaked current. Securely fasten the grounding wire to the side of your house using staples or other zip screw type wire clamp suitable for the job. If you need to bend the ground wire make the bends as gradual and as smooth as possible. Then on a separate lug on the bussbar run jacketed stranded 2 ground wire outside and straight down the side of the house to a ground rod sunk at least six feet below ground eight feet would be better.

There is no requirement to ground an attic antenna in the national electrical code.
