Grounding a sat tv dish in a tear?

[Lgboro]

I understand how to ground a Sat tv dish to the ac side of my electrical, but to use it off grid should it be grounded to the negative of the battery? I would like
the capability in case of natural disasters or power outages and want to do it the right way.

Short of driving in a ground rod there really is no way that I know of. It is only the LNB that has any electrical connection the dish grounding is static electricity protection if I understand it correctly. I have not yet tried ours so can not give a first hand.

Satellite dishes on houses are grounded to provide a low impedance path to ground for lightning strikes. Its not really an issue in a teardrop setting as the dish isn't usually mounted on the trailer. Besides, you've probably got bigger problems than an ungrounded dish if lightning is striking that close to your trailer!
Here's a picture of my dish:
