Anyone ever have a problem with floating platforms messing up the dish?

My 6 footer is built on a deck and i was wondering if anyone ever had a problem the the deck raising at one end due to not having the deck supports below the frost line causing lose of a plume mast? heres hoping that i did go deep enough when i put my deck in!one end attached to the house and the other on posts.Just curious if anyone ever seen this problem with a dish mounted on a platform like a deck.

Yes I have that with my ku dish. The wall its mounted on will warp in low temps enough to loose about 30% signal strength. I will remount this dish in the spring to a location that doesn't have this kind of problem(I hope).
