Hi Didier,
I have one of the Trimble Bullet antennas, that was supposed to be from
a working system, but it is deaf as a post... really dead. Given that
it is supposed to be more than 30db gain, it should do better than any
of the hockey puck antennas.
I wonder if there is a common failure mode in that antenna?

That is probably the best antenna you can get, and it won't break the bank.
I also have a Trimble Bullet, the antenna that was designed to go with the
Tunderbolt. It is a very good antenna also, but harder to find, and it has
lower gain than the 58532A, so at my location (under the roof in Florida),
at the end of 50 feet of good quality 75 ohm coax, the Symetricom unit
works better.
I also have several pucks, including very inexpensive Chinese-made ones and
a very nice Trimble mag-mount puck that is the best of all the pucks I have
(in terms of performance and also mechanical design) and which I got for
$15 on eBay also. They all work, but the Trimble puck is the one I take if
I need to go mobile.
Most the pucks I have receive better than the Trimble Bullet. They are
probably not as good as far as multipath rejection for low angle signals,
but they are more sensitive and I see more satellites with them.

Hi guys,
I have asked this question several times over the past few weeks and get no
answer. Have I been ostracized??!!
Question is that I am looking for suggestions for GPS antenna for t-bolt.
The antenna that I am using now is a no name and I not know where it came
from! Wonder if a Garman GA-30 will work?
