I found one at the local swap meet many years ago for $1. I used that
for years when I only had two gps receivers and it worked fine. Opening
up the top cover you will easily see the circuit. I cut one of the
strip lines from the number two port and inserted a 100 pF DC blocking
cap, and a 220 Ohm R plus RF choke (several turns of thin wire) to
ground. Number one port Rx feeds the antenna and the Rx on Port 2
thinks it has an antenna connected.
With a well sited antenna you will not notice the 3 dB loss.
Now with an 8 way -hp- splitter ($10 at the swap) I don't need it any
more, but the disadvantage is that one is tempted to try to use all
those ports :^(
