had the same issue: was nervous about a long run of ground wire to the nearest cold water pipe.

i pounded the grounding rod next to the foundation right where the signal cable goes thru the wall, and attached the ground block to the wall and then ran the solid core copper grounding wire from the ground block to the satellite grounding rod and then inside the house to the basement where i could clamp it to a cold water pipe, which ties my satellite dish grounding rod, the ground block, and the cold water pipes to the ground of the electrical circuit, preventing a potential difference in ground state on the system.

as origionally installed, the electrical service box was grounded to the cold water feed via a solid core aluminum wire.

i had an electrician install dedicated lines for the hi-fi and video systems, and asked him to add a grounding rod for the electrical service box (in addition to the ground on the cold water feed pipe ) and replace all the aluminum with copper. yes, he laughed at me, and yes, now there is no noise anywhere in either system.

lots of people are having home theater built into their new homes, but the electrical systems feeding them are still in the dark ages. don't count on your electrician or even the HT consultant to have a clue about noise traveling on the neutral and ground circuits.

i recently looked at a "state-of-the-art" cable, telephone, music, video and intercom wiring system: a good idea--put all your noise, signal and current wires bundled tightly together and running parallel all over the house! wooppee ! now you can have all your noise traveling on all your circuits all the time!

having electricians or video installers do your audio/video circuits is like letting the guy who cuts your grass do your hair--they really can't tell the difference.
