I think all GPS antennas need power to bring the incredibly low level signals from the satellites up to a level that'll get along a few yards of coax cable. On the GPS module Pin 3 VANT is connect to the +3.3 V rail and internally to pin 1 ANTENNA IN.
I'm using one of the cheap GPS antennas underneath a slate roof without any issues. Currently:
100% availabilty, 18 tracked, 20 in view, 10 GLONASS.
I checked the Gmm-g3 datasheet and yes, you are right. Thanks for the correction.
