grounding antenna

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

Based on the information you've provided, I can't say that one route is better than the other. I would favor the shortest, most direct path.

Because you have a ground rod at the antenna location, you are correct to bond it to the existing electrical service grounding system... 6 AWG is the minimum diameter wire to be used in this case according to the National Electrical Code. If there was no grounding rod at the antenna location, a 10 AWG conductor would be acceptable per the NEC.
