Keep an eye open at swap meets etc., or even eBay, for something like an
which is a 1 to 2 GHz splitter. It has DC continuity from 1 and 2 to
the common. I put a 100 pF blocking cap in one of the ports, the other
feeds DC to the antenna. An R and choke could be fitted if the receiver
connected to the isolated port complains.
I used one of these for years when I only had two gps units; now a lucky
find of one of the 8 way -hp- splitters serves me well, and still has
one or two empty ports... -hp- did make a four way one but not I
think, a two way.
Incidentally these things and similar are very useful just as boxes with
SMA sockets, for the usual $1 or so they fetch at swap meets, they are
well worth grabbing.
