That's a little smaller than I need, and not easily connected without a PCB.

For a transmitter, I'd just use a wire whip.  But I'm not sure what the 
equivalent would be for GPS - is there any easy way to wind a 
quadrifilar helix?  I know Garmin does it in some of their products 
using flex circuits, but that's a little expensive to get set up.

In two places, no less.  Fixed it, thanks.
