what if the antenna is damaged in the crash?
Then there is the question of whether or not the unit will acquire a signal while inside of an aircraft.
Good questions with no clear answers, as least AFAIK. The antenna is like a piece of metal strapping and is really tough. I doubt it will break. The attachment to the unit itself looks pretty robust, but I haven't taken it apart (and don't intend to). I'm more concerned about being sliced by the antenna with it extended while the unit is hanging on a lanyard around my neck. Ouch.
Even if the gps can't get a fix for whatever reason, there's a chance that the 406 transmitter will ping a satellite. It's not as good as having the gps fix, but it's still a lot better than 121.5.
So I guess the tradeoff is protecting the antenna so that you can extend it after the crash vs. risking the antenna in the event that you're knocked out and unable to deploy it after the crash and fate nonetheless allows the unit to see a satellite.
