[time-nuts] GPSDO 10MHZ Splitter

[Bob kb8tq]

Hi

Cheapest and easiest is to use a power splitter. Ones from Mini Circuits that are
rated to work at 10 MHz can be had for $20 or less. At some point you run out
of power ….

Building a splitter from NC7SZ125’s is not a all that crazy as a DIY project. You 
can get a dozen or so outputs and still not spend twice what the eBay splitter 
would have cost you. Cost is a bit less if you are happy with TTL out as opposed
to sine waves. ( = you don’t have to spend money on the coils for the T networks 
in the output lines). 

Either way, the signal is pretty well isolated and as clean as it was coming out of the 
GPSDO.
