I have a eave mounted Satellite mast with a #17 copper coated wire running to a coax ground block about 28' feet away. From there I am about 36' from the electrical service ground rod. I am considering driving an 8' ground rod near the coax ground block and running 2-#10 copper (one for the mast and one for the coax) to the new rod and then running #6 copper from the new rod to the electrical service rod. Do I need both #10 wires to the new rod to meet NEC code? Should the #6 copper be buried and if so how deep? Any other suggestions? I can not relocate the mast or the point of entry for the coax.

IF that #17 cu is the messanger wire attached to the coax your all set with the dish being bonded, just need to tie that wire to the grounding block, and bond the mast with # 10 cu, I use #8 cu, you are only allowed 20' of wire so sounds like you need to drive a ground rod, bond the mast and the grounding block to the ground rod, then bond the ground rod with #6 cu to the Electrical Service ground rod... and you are good to go...
the reason you can use the messanger wire for a ground is because it gets bonded with the coax shield at the grounding block...

Just as long as the #6 is free from exposure to physical damage.
Only true if the satellite [antenna] is a community-based system falling under Article 820.stickboy1375 said:
Additionally, if this is not an Article 820 system, the #17 copper-clad steel or bronze conductor running from the ground block to the dish [usually bonded to the mounting bracket foot] serves as the mast ground, provided the grounding block is adequately bonded to service ground. An additional conductor to the "mast" is not necessary.

It is my intention to use #17 copper-clad steel as the only conducter bonded at the dish bracket and the ground block. Additionally I will run a #10 cu from the point the #17 terminates at the ground block to a new 8' ground rod, as well as an additional #10 from the ground block to the new rod. Finally I will run a #6 cu from the new rod to the existing electrical service ground.
