Strip cable as shown. Be careful not to nick center conductor or outer braid.
Twist outer braid in a clockwise direction so that at least 1/32" of cable dielectric is bared, and braid is left flat. (stray or loose braid can cause shorts.)
Gently insert center conductor into back end of connector, "feeling" it into the guide hole. (if center conductor is not properly in place, about 1/8" of center conductor will show at the back end. Reinsert until cable dielectric reaches position shown in illustration.)
Push the cable firmly in place (as far as possible). Then screw the connector onto the cable in a clockwise direction until it stops. Assembly is complete.
