I tried a similar Garmin antenna with my Datum ET6000 and the lock times were really long, even with the antenna on a 14 foot pole above the roof. I attribute a lot of this to the long 8 ft RG174 style coax pigtail. I have to wonder if the gain of the preamp as published actually includes the inherent cable loss, and even if so the preamp must be screaming in gain to make up for the loss. I intend to get a proper antenna.

Here is a comparison of specs of these type antennas:
