Because my satellite dish is mounted under the roof eve, I'm not concerned about a direct lightning strike to the dish. No ground strikes will propagate through the incoming dish ground - it's not traveling through earth. I bucked the NEC rules, and grounded my incoming satellite dish ground to a cold water pipe. At least some grounding is required for the dish, to provide static discharge for the dish.
My irrigation controller and invisible dog fence are plugged into a point of use surge protector (Tripp Lite Isobar). If I could, I'd bond their ground wires to the house ground/rod, but it's about a 30 foot distance, across a 3 bay garage. I don't know if this SPD will be at all effective, in this manner, but it's what I've done. If we add a pool to the back yard, I'll trench the driveway, and bond all 3 to the house ground properly, at that time.
For a few hundred dollars, the engineer may provide some peace of mind.
