I noticed on GlobalSat's website (and other sites), a number of different external GPS antennas.
I know these are not a GPS receiver, just antennas for a receiver, but most GPS receivers have an internal antenna and (AFAIK) no way to connect an external antenna.
Mounting an external antenna might be preferable to mounting the entire receiver externally, but what GPS receiver, if any, is out there that can use them?
I suspect that these external GPS antennas only work with some specialized receivers.
