I'm trying to properly ground my roof mounted antenna. I have come up with the following two options:

1.) Run #10 thhn stranded wire from the antenna mast to the coax grounding block at the point of entry. Run #10 thhn stranded wire from the coax grounding block to a driven 4 ft copper ground rod. Run #6 thhn stranded wire from the 4 ft copper ground rod to the system ground.

2.) Run #10 thhn stranded wire from the antenna mast to the 2" rigid riser. Run #10 thhn stranded wire from the coax grounding block to a driven 4 ft copper ground rod. Run #6 thhn stranded wire from the 4 ft copper ground rod to the system ground. Similar to the picture below except I will be making the connection to the rigid riser above the roof jack.



Option 2 is preferred because I wont have to run the #10 thhn stranded wire along the roof, around the awning, and down the brick wall to connect to the grounding block. Thoughts?

Option 2
