satellite dish grounding

My 10' satellite dish is 250' from the receiver. A recent lightning strike blew out the receiver and who knows what else because we won't know until the receiver gets back repaired.

To ground this entire system is a ground rod and #10 AWG copper connected at the dish site then with 10 AWG copper back to the main service ground, a grounding bar with the coax cable fastened, then #6 AWG copper to the main service ground enough?

The dish was installed about 8 years ago and no problems 'til now but this site has shown me the installer left out something rather important and now expensive to do right.

What do you think they left out?

810.21(H) Size. The grounding conductor shall not be smaller than 10 AWG copper, 8 AWG aluminum, or 17 AWG copper-clad steel or bronze.
IMHO if your satellite dish gets a lightning strike no amount of additional grounding will protect it.

on top of the ground rod, the probably sunk a big steel pipe into a big chunk of concrete that the whole thing is mounted on. probably the pole and concrete is a better grounding electrode than the ground rod anyway.

I also think it is unlikely anything economical would have saved your equipment from a direct lightning strike.
