Hi Chuck:
Can you tell me the model number of that antenna?
Have Fun,

Here is the standard antenna for the T-Bolt. Not a helix, but
rather some sort of crossed dipole.
The feed point is the corners of the two V shaped elements, forming
a sort of bowtie >< With the ends capacitively coupled to the
ground plane.

If anyone can tell me the desirable characteristics of an antenna for
GPS, I would like to know. The antenna will be mounted outside and
needs to be waterproof, so I'm not looking to fit the antenna in a
small package.
most GPS antennas are helices of one sort or another (quadrifilar is
popluar) and
helices are broad band enough that designing for one gets you all
frequencies.
There are also a fair number of microstrip patch antennas out there,
but they tend to
need stacked patches to get L1, L2, and L5
