1. Identify connector parts. (3 piece parts)
2. Strip cable to dimensions shown. Do not nick braid or cen-
ter conductor. When stripping LMR-100 low loss cable,
remove foil back to where cable jacket is stripped. A wire
stripper of correct size is recommended for this step. Twist
stranded center conductor into tight bundle and tin (op-
tional). Slide crimp sleeve onto cable as shown.
3. Flare braid and slide cable into body making certain that
the cable insulation bottoms on center contact. Solder
center conductor to contact through the rear access port.
Use a minimum amount of solder for a full fillet joint.
.020
(0.51) diameter solder is recommended.
4. Arrange braid uniformly around crimp stem. Slide crimp
sleeve over braid and crimp securely using recommended
crimp tool. Place expansion cap in access port and seat
with .187 (4.75) diameter flat punch. Shrink heat shrink
tubing over crimp sleeve if applicable.
