No, just just a regular GPS unit I had sitting around.
The point wasn’t to test the various antennas available but to answer / proof of what affect shielding has on GPS receivers and the signal quality.
There is also a test that Tridge has done which compares the various GPS units. That I understand that was just a comparison out of the box over a few hours to compare results. No shielding was used in that test. …At least can’t see any in the photos.
