Spark Fun has the Sarantel SL1204 Helix antennas: .8 dB NF 18 dB gain small size. 1.8 to 3.6V supply. Dielectric loaded helix. $22.00
Made to work with small near field. These should work with modern GPS receivers very well. I'm awaiting a couple of small diameter cables with SMB connectors to solder on to connect. Application data says that a ground plane will improve gain so maybe a real ground plane will not detune. But there is no information on what using a choke ring to suppress multipath does. Any comments?
