I use to use splitters that were rated for satellite dishes (Like
directtv and dish). They down convert to 900-1.5 Mhz and they also pass DC.
As time went on and we time nuts strive to do it right, I switched to
Mini-circuits splitters and bias tee's.
If any of you need it, MiniCircuits ran group delay test on their
ZA4PD-2S splitters for me. The document is about 70 some odd pages.

an MCL ZAPD-2,

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.
