Funny you should ask.. I do have a solution that works for me. the KAP.
This is a cover (the blue thing) for the rain bucket. It's used to cover the bucket during the winter to prevent accumulation of snow and ice. This is better than anything I have seen . It goes on and off easily, yet won't blow off in the strong Iowa winter winds.

The pictures are a few years old and my unit didn't have the retrofit kit on it yet (same wire antenna there) so I have had the opportunity of having the KAP several winters. It hasn't fallen off or blown away ... yet...
