bonding @grounding satellite dishes?

[wireman1]

what article wold you use to for the proper grounding @bonding for the large satellite dishes that the local cable will be installing.threre will be 6new dishes in a romete area no building near by.does each dish need a ground ring around it and must you bond all the ground rings together from the dishes to form a gounding system?"

I am going to go out on a limb here, and take a stab at it. Under no circumstance am I in any way comfortable with this answer, but it is something to start with.

I am going to say, yes, you do need to connect to a grounding electrode at the remote structure (the post with dishes on it). Reference: 820.100(B)(2).

The language calls for you to connect to one electrode; however, it would not be a bad idea to connect other electrodes to the system if available.

There is no requirement for a ground ring that I am aware of. It appears you could drive a ground rod, connect all the dishes to it, and call it a day.

Are there any 120V outlets of any kind out there?

The NEC doesnt apply to cable TV utilities, does it?

I think it does, at least where it attaches to and enters the premises, somewhere between Art's. 820 and 830.

there are no 120 outlets on site as of this date.If there was would it make a difference?

Wireman, you can quote my PM here if you want, I'm late for work now.

Looking to the NEC to answer this question would be foolish in the extreme. The NEC is a safety code, and will protect life, but will not provide the design information necessary to provide protection of sensitive communications electronics.

_Design_ your grounding and bonding per the requirements of the electronics, and then confirm that this design additionally meets the _safety_ requirements of the NEC.

810.4 says that a community television _antenna_ must comply with article 810, and that the distribution of the signals from the antenna must comply with article 820.

810.21 describes grounding. There is _no_ requirement of a grounding electrode at the antenna; it is all about bonding back to the structure with the electrical service.

From general concepts in article 250: if you for design reasons add any grounding electrodes, even those not required by the NEC, then you _must_ bond them all together.
