Some practical tests today with the antennas I measured in The big Antenna S11 catalog. I used three identical GPS tracker devices running exactly the same code. The three trackers were always kept right next to each other while I was driving. The order of the three was changed a couple of times during the day. I believe we have a clear winner here, and this was also the one that won the S11 test.
