[USRP-users] GPS antenna with power splitter
There is no difference but at least 3dB loss for GPS signal that has no
noticeable adverse effect on GPSDO performance

Hi.
I have two USRP B200 and each USRP is equipped with GPSDO. Also, I have
one 5v active GPS antenna, and one power divider(1 input and 2 outputs) whose
operation frequency is 0.7~2.7GHz.
In power divider, the input port is connected to the GPS antenna and each
output port is connected to a different GPS ANT port on the USRP B200.
I want two USRP B200 to receive GPS signal from only one antenna. That's
why I use power divider.
So, I wonder this configuration works well compared to two GPS antenna
configuration (i.e. each USRP are connected to their own GPS antenna).
Is there "any" dis-advantage compared to two antenna config?
I tested it and observed that both USRP's GPS ANT LED was "green" and
seems to work but not sure. I executed the sync_to_gps program for both USRP
and it worked well.
Thanks.
Regards,
