I use an AeroAntenna AT575-90 choke-ring antenna:

They are available from time to time on ebay.
It is by far the best GPS antenna I have with respect to timing and
position stability, presumably due to superior multipath
rejection. It also will work indoors where other antennas will
not. Regarding immunity from interference, it rejects the crud put
out by my digiscope better than the others, but that is hardly a
systematic test.
Best regards,
Charles
