Yes, it is a good question.

I have been buying a lot of cheap GPS antennas for testing on RasPis.

I plug the antenna into a GPS, then just wait until the GPS gets a good
sky view, and then check the sat SNRs.  Replace with a different antenna
and repeat.

The difference in SNR between similar appearing antennas can be very
dramatic.  Some are clearly strong or weaker than others.
