The UG-1185A is the designator for the "Captivated Contact" style
N connector for RG-8 and RG-213. And this is the connector AND
CABLE to which most are referring. What is out there for various
types/sizes/brands of HARDLINE is another issue.
On 2000ft of 7/8 hardline the differential expansion of the center
versus shield can have enough force to drive the center pin and center
conductor right through the side of a cast aluminum box! More than
enough force to pop a Teflon washer out of its captive position. But
when dealing with cable having a braided shield, the captivated
contact will hold the center pin in position under most circumstances.
It is MUCH better than the old style UG-21x type of connector, but
useful only on 8/213 type cables.
