Verify all parts are present. 2. (a) Cut outer jacket and shield 5/16” (7,94mm) from cable end to the depth of the dielectric. Remove outer insulation and coax shield. (b) Cut 3/16” (4,76mm) from the cable end to the depth of the center conductor and remove dielectric exposing center conductor. 3. Slide center pin contact onto center conductor, all the way against the dielectric. Solder or crimp to center contact. 4. Slide clamp nut, washer and gasket on to coax cable. 5. (a) Slide ferrule over dielectric and under the coax braided shield. (b) Verify that ferrule is pushed up against outer jacket . 6. (a) Push assembly into body until center contact “snaps” into body. (b) Slide clamp nut, washer, gasket All dimensions are in inches.
