Grounding An Antenna In Attic

If you need to bend the ground wire make the bends as gradual and as smooth as possible.

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. The mounting rod is insulated from any of the active reception parts. 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. So there isn t any ground from the tv either to bleed off any voltage that might pass through the antenna.

From your description it sounds as if you may create a ground loop which may cause problems throughout the house. Neither apply to an antenna in the attic. Stick to the building code. 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.

Air movement in your attic should not pose a problem. But first check the electrical plugs of the various devices attached to the tv line. Run a length of 6 jacketed stranded ground wire from whichever you installed there directly to your bussbar. There are very specific requirements for grounding an antenna both via mast ground and a shield ground.

Securely fasten the grounding wire to the side of your house using staples or other zip screw type wire clamp suitable for the job.
