Just about all COAX splitters and devices contain a grounding lug now. You should just run your ground wire from the first one to the building's grounding electrode. It is not proper to drive a separate ground rod just for the SATV wiring. Don't forget that the dish itself must be grounded as well; not just reliant upon the coax shield. In most cases, the shield never actually comes in contact with the dish at all.

The optimum location for your dish is near the service entrance if you can see the satellite from there. Then you have easy access to the ground electrode system with a short grounding conductor. When you are grounding out lightning, the shorter the conductor the better. I would still drive a separate rod for the dish, directly under it and bond that back to the GES.

The dish is at one end of the house and the panel is at the other end not that far about 40 feet. what size wire should that be #6. The biggest question is why wasent that done when it was put in.direct tv free install nothing free about direct tv every time you turn around your getting a notice about a rate increase. guess that what happenes when you live in the sticks and they are the only way you can watch tv..

#6 is fine to bond them together. As to why they didn't do this: It all comes down to the installer. They usually work as sub contractors and are paid piecemeal, so the fastest way in and out is usually all that you get.

Hence, 250.95 ('08 NEC) requires the intersysten bonding location.

BTW, the dish guys here are not much more professional in the workmanship dept.

Heck, last week I came upon a pipe clamp on PVC at the meter! I thought they outgrew that stupidity.
