Try to keep your ground wire runs as short as possible and avoid making 90 degree turns or bends.

The mounting rod is insulated from any of the active reception parts. There is no requirement to ground an attic antenna in the national electrical code. But first check the electrical plugs of the various devices attached to the tv line. If you need to bend the ground wire make the bends as gradual and as smooth as possible.

Neither apply to an antenna in the attic. So there isn t any ground from the tv either to bleed off any voltage that might pass through the antenna. 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.

Run a length of 6 jacketed stranded ground wire from whichever you installed there directly to your bussbar.
