Listen to Jim, guys. THE most frustrating thing in troubleshooting is
when the "trouble" is in the cheap/low quality parts used in an assembly.|
ALWAYS buy the best you can find/afford. Buy the best; buy once. I have
a FEW more vendors than Jim, but his point is nonetheless valid and
should be added to the HAM Gospel:
Thou shalt not use cheap crap in thy signal line. <grin>
This is ALSO why I have eliminated ALL UHF connectors from my station.
GOOD ones work fine. Not as well as N and others, but good enough.
Problem is that too many of the connectors/adapters with UHF on one end
are made like crap or have a fatal flaw in them somewhere.... just a
matter of a short/inconvenient time to failure.
Be well!

More possibilities. Back in Chicago, I traced an intermittent in an
antenna to a junk connector adapter. After getting back on the air in
2003 after 20+ years off, I made the mistake of restocking my parts
stash with junk adapters from a Chicago flea market. Over the next
five years, I traced a half dozen failures to them as a cause. My
definition of a junk connector is one that isn't stamped "Belden," or
with a MIL part number, or one of the types made for hard line.
Perhaps a ferrite choke that is poorly designed, under-rated for the
specific use, or used with a badly imbalanced antenna has failed. They
do that. :) And, of course, loose connectors.
