So cleaning the snow off my car this am the antenna cover got knocked off. The cover broke and left all screws in the black plastic part. A quick google search tell me that this not a quick/cheap repair. Is it possible to put a couple dabs of silicone caulking to hold it in place? I've got pictures if anyone wants them.

(I have cross posted this on another message board since I need an answer quickly. Sorry for the bad forum etiquette).
