quick fix sky reception after snow storm

There seem to be two methods, which are dish height dependent.

(1) lower dish. Hit it with a broomstick to dislodge ice and snow.
(2) higher dish. Throw a football at it to dislodge ice and snow.

I have used both methods successfully, although I expect they are frowned upon by Sky.

* I know the picture is of a barbecue. The Sky dish picture was a bit too blurry
