Can you open them up and see how they are made and what they use for the
gain device?
Take lots of pictures :)

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).

Chuck,
I have one of the original red box TB. It came with the Trimble Bullet
antenna
that is specified in the TB datasheet.
The antenna works but gives extremely poor results. The TB works much
better with
the Symmetricom antenna that is sometimes available on eBay.
The Bullet antenna is usable with other GPS receivers, so I know it is
not bad.
Its just a poor match for the TB.
