When I only had two gps units in the dim and distant past, I used a 
passive splitter made from a Minicircuits (MCL) ZAPD-2 unit bought at 
the swap meet for $1, with a 100 pF series blocking cap in one of the 
output ports.  If the receiver connected to the other port complains, 
you can add some resistance to ground to fool it.

There are more expensive ways of doing it...
