Looks good, but no reports on it yet. u.fl is OK, but a PITA. The antenna does not specify it works with Galileo. You want at least 15MHz to 20 Mhz for Galileo E1. A "GPS" antenna is often not good enough. A good antenna would be marked as good for Galileo. GLONASS needs a much wider bandwidth, but timing people turn off the GLONASS as unstable. For the price you can buy a better antenna if required. RGDS GARY --------------------------------------------------------------------------- Gary E.
