Grounding a dish

Apparently concepts in this picture were misunderstood or simply ignored. The picture is chock full of details specifically relevant to your questions. You are still asking same questions answered by that picture in thread entitled "NEC 820-40".

If dish is a separate structure, then dish is earthed separately. AND wire between two structures (dish and building) is earthed where wire enters each structure, as defined in section 820. Major expense? A $1 ground block and some 14 AWG wire. The point of that previously posted figure from a company specializing in this stuff. Please look carefully at this figure. It answers your question:

Dish can install whatever they want. You remain ultimately responsible. No need to install a $1000 earthing system. Somehow reams of technical facts have you thinking this is a $multi-thousand solution. Dish must put wire into the building at the service entrance - using a short 14 AWG wire and $1 ground block on their incoming wire. From what was described, they could not be bothered assuming you would blame lightning, rather than them, for any damage.

Do you really care whether it is Section 800, 810, or 820? No. Important concept remains same. Any wire entering your building must first make a connection to dedicated earthing connection - the building's single point earth ground. Its just not that complex as demonstrated by the figure from

For earthing improvement, each single point grounding system in that figure is interconnected by a buried ground wire.

If code is too cryptic, then spend many m> See that is the thing. The dish comes with a free installation according to NEC 810-40. I agree that NEC rules must
