One of my very first questions should I be so lucky to go to heaven when I expire is to ask for the real poop on grounding.
I've seen electronics with 3 prong cords, and 2 prong cords, I've seen a very highly skilled sat installer blow up a receiver just by plugging it into a wall outlet, I've been shocked on antennas and different electronics in a variety of homes. I've seen an improperly grounded satellite system survive a lightning strike that hit a tree 5 feet from the dish, I've seen properly grounded coax turned inside out by lightning (seen the reverse of both of those too).
I don't know that I would consider any 'universal' grounding strategy as 'correct', and sorry to say, but I roll my eyes when any installer cites any procedure as gospel.
As for my business, I follow whatever the service provider wants. When it's up to me, I follow the 'octopus' theory (everything grounded to a single point) and I advise customers I really like to see a whole home surge on their electric panel. (Menards has them for around $60). I'd rather see that than a $200 outlet strip. (LOL, but I do have a $200 outlet strip in my home on the big plasma system).
Hopefully (it's all we have) you get by and lightning doesn't pay a visit, and the light company does their job.

• The AC unit service enclosure is not compliant.
o The AC service frequently uses a ground wire that is smaller than what is required by
the NEC for DIRECTV.
o The AC service ground is not designed to handle the additional voltages introduced by
the DIRECTV, Inc. system.
o A future change in AC wiring may eliminate our ground.
o Metal boxes and conduit installed to support the AC unit may not be made electrically
continuous to the service panel.
o Use of an AC grounding wire introduces potential differences that could put an IRD at
risk from unwanted AC unit induced voltages.

If the dish had been installed on the side of the house where the electric meter was, it would have been attached to the ground block which does into the ground.
LOS stopped that from happening

I'm happy with it. Gosh, it isn't POWER ground. It's STATIC ground designed to run any static electricity from nearby lightning to ground rather than into the house and into the tuner or whatever electronic device the shielded cable is going to from the ground block.
So, experts, was this done correctly or not?
If you live in lightning storm areas, pulling the plugs and cables from the equipment during storms is the most reliable way to protect your equipment.
Ground LOOPS are another thing related to improper power grounding and not closely related to this grounding topic.
