We are just finishing up the rough wiring for a new single family dwelling and today the GC informed us that the low voltage contractor wants us to provide the ground for his DBS satellite dish. The house is about 6000 sqft with 3 levels and the dish is located at the opposite end of the house from the electrical service. It would take approximately 150? of wire to connect the dish directly to the grounding electrode system. 820.40(A)(4) says the grounding conductor shall not exceed 20? or a separate ground shall be used. Even if I did install a ground rod closer to the dish I?m still looking at 40?-50? of ground wire to reach the dish and then another 100?+ of wire between the ground rod and the existing grounding electrode system. 820.40(B)(1)(1) permits the interior metal water piping to be used if the connection is with 5? of its entrance to the building. This point would be at the same location as the service so doesn?t help much. This house is being built under the 99 NEC and I don?t see the 5? limit in 820-40(b)(b). All of the interior piping is copper and there is piping pretty close to the dish. Suggestions anyone?
