Never seen uhf connectors in military.  Lots of N tho


My two 500 foot RG-216 military surplus cables both
eventually exhibited retracted pins on the type N
connectors at both ends.  I replaced them with PL-259's.

My 150 foot RG-218 military surplus cable
had type N connectors with captivated center pins.  However,
the center conductor of the coax eventually retracted
from the internal socket that the connector received
the cable with.  Of course, the RG-218 is way too big
for a PL-259.  So I had to disassemble the type N,
expose more center conductor, and then reassemble.
Fortunately, it is of the "clamp" style and hence
reusable.  The RG-218 has been hanging from my 106
foot tower using a Kellems grip for around 10 years.
It also coils or uncoils whenever the tower is cranked
down or up.

Success anecdotes about install once and never touch again
commercial sites are probably not relevant to ham applications.
