If you search on GPS antenna splitter, sans Narda, you can turn up a
bunch of stuff. What I found were choices between passive devices
with unacceptable 4-8db insertion loss, or amplified units at
startling prices.
There's even a curious homebrew at pacifsites.com/~brooke/4GPS.shtml
with diodes for DC blocking, and atrocious screw-on Radio Shack BNC
connectors. I wouldn't use that in an airplane on a $3,000 GPS,
though.
