1. Identify connector parts. (4 piece parts
except RG-58)
2. Strip cable to dimensions shown. Do not
nick braid or center conductor. A wire
stripper of correct size is recommended for
this step. Twist stranded center conductor
into tight bundle and tin (optional). Slide
crimp sleeve onto cable shown.
3. Flair braid and slide cable into body making
certain that the cable insulation bottoms on
center contact. Arrange braid uniformly
around crimp stem. Slide crimp sleeve
over braid and crimp securely using
recommended crimp tool.
4. Solder center conductor to contact through
rear access port. Use a minimum amount
of solder for a full fillet joint.
.020 (0.51)
diameter solder is recommended.
5. Assemble insulator if applicable then place
expansion cap in access port and seat with
.156 (3.96) diameter flat punch or MCX
hand assembly tool 141-0000-908. Shrink
heat shrink tubing over crimp sleeve if
applicable.
