I agree with Rolf, I really don't see earthing the LNB as doing much to save it.

Unplugging everything in a storm is the best option IMO, but not always practical I know, and won't do much for the poor LNB.

Everything else is might reassure you and offer some protection, but don't count on it. UPSes aren't even that reliable with a direct hit to the power line, however but the makers might offer some insurance on damaged equipment connected to the UPS.
