So I  have a bunch of these mini-circuits splitters that cover 500 - 2000   
Mhz. It has continuity on all ports. Has anyone tried something like this  to 
use  
a single GPS antenna on 2 receivers? They both put out 5  volts on the center 
 
pin. Maybe a cap on one of the  ports?





Hi,
 
I use a resistive DC-4GHz  minicircuits splitters with  success, both antenna 
ports providing 5V.
 
I also have used just a simple BNC TEE surprisingly without any  problems 
whatsoever. Sometimes that works better than an Agilent 1-to-2 splitter  since it 
doesen't add any amplifier noise.
 
Don't connect a 3V configured GPS with a 5V one though even though the  ports 
are usually overcurrent protected.
 
bye,
Said
