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?
