The large nut tightens down on a collet that clamps the coax. If it is over tightened, it will crush the outer shield and deform it. Maybe even short to the inner conductor? Are any connections loose? If you wiggle them while observing the output, you might find something. You might open one to see how it is arranged.
Good luck,
Tom

Thanks for the hint!
So, if that is the case, what would you do to fix it?. I mean, is it a
good idea to disconnect them to check?. I have no clue of how the mating
is made... is there any online picture of them?
Regards,
JOSE
