The satellite dish is on the roof. I would ideally like to bring the two cables right thru the roof into the attic, as I have full roomy easy access to the attic and can readily route the cables from there. Intructions with the dish only describe bringing the cables down the roof and thru a sidewall. Does anyone know a good trick for passing cables thru the roof (shingles and all) without creating a leak?

I've obviously put the satellite mounting bolts thru the roof, with liberal sylicon sealer around and under them. Two cables won't exactly fill a hole, especially if the cable ends have to fit thru the hole first.

Secondly, what's the best trick for grounding it all, if I go right into the house? In the old days when I had a roof antenna I used a radio shack cable grounder. The antenna cable passed thru it. It was plugged into a grounded wall outlet. Is there a similar device for satellite cable? Am I at serious risk if the dish remains ungrounded?

Thanks in advance,

Dave
