I’m only peripherally part of the group, and not particularly smart, but seems to me that shouldn’t be too hard to fix – depending how it’s broken.  It looks vaguely like a coaxial connector – what the rest of the antenna, inside the rather think casing is like, I’m not sure.  Perhaps it can be fixed by re-attaching the connections and then sealing it impenetrably with lots of silicon – I’m imagining the seal is a key part of the issue.  Mind you, such a “fix” will never be as robust as the original construction, so if it is going to suffer abuse then likely that is an issue.  I’m forwarding your question to some contacts…

Otherwise there must be an electronics person in the group!
