Hi Didier,
I don't quite know what to say about that. Trimble seems to think that bullet
antenna is the right thing to use. Somehow, I would think they should know.
It is possible that they are prone to failure, I guess...
It is surprising to me that the only antenna I can get to work is a Motorola
puck that is supposed to be too low gain (and is).
