ground paths via GPS can be a real issue. I have found that the
Time Machine stuff is very bad.

course right that it is desirable to not have a GPS splitter
introduce ground loops between Kiwis.
Steve I have been very successful using simple satellite
splitters like this one available from amamzon.fr
for 16 euros:
At KPH and at
AI6VN/KH6 I put the GPS antenna on the roof and ran 30M of
RG-6 to the splitter, then directly connected the splitter
output to the Kiwis and have run that way for years without
problems. The RF signal gain from having the antenna on the
top of the roof more than makes up for the 12 dB signal loss
in the RG-6 and the additional 10+ dB in the splitter.
I use no DC
blocking. Test the RFI level with and without the GPS
connections to the Kiwis to see if introducing the splitter
adds to your RFI. If so, then a specialized splitter is of

Lots of splitters available but they all end
up tieing grounds together which can make a bad situation
worse and more complex.
Complete low frequency isolation is
desireable but requires special effort.
