Electrical – Bonding Ground Rod for Rooftop Antenna

electricalgrounding-and-bondingtv-antenna

I am installing a rooftop antenna on the end of my house, opposite the end where the ground rod is located.

I plan to install a new 8' ground rod on the ground directly under the antenna. I need to connect (bond) the new ground rod to the old ground rod. I plan to do this with 6 AWG copper wire. Because of a variety of obstacles, running the 6 AWG around my house to the existing ground rod would be difficult.

Would it be safe to run the 6 AWG bonding jumper in PVC conduit through my semi-finished basement? For example, attached to an unfinished concrete wall?

Edit: I've ended up running the 6 AWG in the ground around my house. I could not find any good information about running it inside versus outside, so Iopted for the safe route, to keep it outside.

I've cleaned up after lightning hits an antenna, and designed spark gaps to protect electronics. The last thing I'd do is install a lightning rod through my basement. That stuff should stay outside, irrespective of NEC 810.21(J). Ground loops are not a serious concern in this particular application.

I'd also consider changing the 8' rod into two 4' rods, which are far easier and safer to drive into the ground.
