Here’s a few:
... lots of ebay offers snipped
The problem is, they will do their Job at RF, but the GPS receiver
usually has to feed the antenna pre-amplifier with DC through the cable.
The 4 RX candidates should not have to fight for the right / duty to do
this,
with their possibly conflicting offers. Given that DC makes it through the
transformers (or whatever) of the splitter of choice at all.
So, probably a bias tee is needed also, and some replacement dc power
source, which is the easy part.
Also, the 4 receivers should not see each other DC-wise, although there
is usually a protection against catastrophic abuse.

I'm looking for a splitter to allow three or four GPSDO's to share my
roof-mounted Lucent PCTEL KS24019L112C 26db GPS twist antenna.
I understand from scanning past threads that inexpensive splitters by companies
like Mini-Circuits often turn up on eBay, but I'm having trouble narrowing down
to one that will work for my situation. Can anyone recommend a specific
splitter that wouldn't be too expensive?
