If the data sheet doesn't say anything about the power supply requirements, 
I'd assume it is a simple splitter with no amplifier which would match 3 DB.

The HP 2-way and 4-way GPS splitter is often available on ebay.  I forget the 
model numbers, but it's pretty obvious.  There are only a few of them.  They 
take power from the coax.
