Step 1
Step 2
Slide the outer ring over the cable jacket.
Trim the cable as specified in the table. Insert
the cable dielectric and center conductor
into the inside diameter of the inner sleeve.
Then solder the center conductor to the coax
center contact.
Slide the outer ring forward until it is flush with the
coax shell containing the braid between the outer
ring and the inner sleeve. For solder type coaxes, soft
solder the outer ring to the assembly thru the cross
drilled solder hold. For crimp type coaxes, crimp with
the appropriate tool in the area defined.
