Michael - What is the UG number of the coax connector? Some connectors made by Amphenol use their own part number(five or six digits?) rather than a UG number, but they usually conform to the UG spec. Once you find the number, get online and Google "Assembly instructions for UG xxx" , or the Amp Part#.
The instructions will include what coax to use and how to properly assemble the connector.

Hi:
Ok. have a right angle solder less BNC connector. Now,
how do you connect coax to it?
reason - hooking to my antenna for radio meteors...:
I know the center copper piece goes around the screw and
is tightened.
NOW:
1) Does the sheath attach to the arm that gets
crimped?
2 ) Do you cut the sheath away and just leave the coax
and center piece?
Why I ask,... well I'm told IF I leave
the sheath when I test the antenna
with an Ohm meter I'll not get 0
Ohms.
but looking at Youtube videos, the
majority connect the sheath !
Now with out sheath I get 0 Ohms... with sheath I get 1.9
Ohms...
so which way is correct? 1 or 2?
Clear skies
