I Purchased 5 used Mini Circuits 3dB splitters from China for about $28 on eBay 
including shipping from half way round the world. 
5-500 MHZ with SMA connectors
Model ZFSC-2-1

Lots of uses for them, splitting 10MHz standards, dual receivers on single 
antenna etc.

I did previously build a 3dB hybrid from a design in an ARRL handbook many 
years ago when I wanted to do some 2 tone testing on a receive converter, but 
with the availability of good quality surplus nowadays it isn't worth the time 
and effort!
