This is a common problem with some rear window defroster units.  The
laws of physics tell us that matter cannot be destroyed, and this is a
perfect example.  When using the rear window defroster to melt snow,
that snow has to go somewhere and the radio antenna is often the path of
least resistance.  QED: you wind up with snow in your radio reception.

As for a solution:  My E28 535i has a specially designed antenna mast
that will not extend in cold weather no matter what you may try.

sometimes not even in warm weather...
