Hi there,
thank you for all the information.
I'm using a bullet antenna (don't remember the maker), on top of my
office. Cable has 50ohm impedance (ultraflex 7) and average quality N
connectors. Patch from splitter to receiver is 50ohm as well, but still
using RG58, will upgrade it asap.
Update on my issue:
Yesterday I made some testing, removing the splitter and nothing changed
(apart the samsung complaining about signal loss :) ).
I removed the trimble board from its case, I gave a look to it and
powered up again: well... may be a kind of magic but it works. Now the
status led is blinking fast and this is the output I get from commands:

So far, so good.
PS: I don't belive in magic, so I guess that some glue I used to hold
the board, added some capacitive side effects. Let's keep it going,
wating for a new GPSDO to join the collection.
Best regards!
