Folding your sat dish: Beaufort Scale?

Probably a 5, or when the trees bend to 45degrees 

When the van starts rocking and the signal starts to break up, stow the dish.

Our 85cm dish was flattened by a nasty gust of wind at Trewethett Farm Club site a couple of years ago. Unnecessary expense to have it replaced and lesson learnt.

OH is a "better safe than sorry" person, so probably a 4/5 for us!  Also, when going out for some time, he folds it down if it is a bit windy, just in case it gets worse whilst we're not around.  Ours is a 85cm dish too.

Damaged the support and motor mountings of the dish beyond repair. Luckily the roof of the van was not damaged DD.
