I have a grounding rod right next to the antenna but now need to connect that to the main house ground.

Our main house ground comes up from inside the wall into the breaker box and it is cement outside the wall in that area and our exterior is stucco.

Is the best option to bring the heavy gauge copper wire through the wall into the garage and then go down that wall, cut an opening from the inside the wall and clamp it onto that wire there?

Or should I go in through the attic and down the tube all the wiring comes up from the breaker box into the attic and hook it up there?

Any help is appreciated
