[time-nuts] How can I measure GPS Antenna quality?

Is that even a sensible question? Is there a better way to phrase it?
The problem I'm trying to avoid is that the weather and the satellite
geometry change over time so I can't just collect data for X hours, switch to
the other antenna or move the antenna to another location, collect more data,
then compare the two chunks of data.
The best I can think of would be to setup a reference system so I can collect
data from 2 antennas and 2 receivers at the same time. It would probably
require some preliminary work to calibrate the receivers. I think I can do
that by swapping the antenna cables.
If I gave you a pile of data, how would you compute a quality number? Can I
just sum up the S/N slots for each visible/working satellite?
