1. Identify connector parts. (2 piece parts - except
bulkhead)
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. Slide crimp sleeve onto cable as shown.
3. Flare braid and slide cable into body making
certain that the cable insulation bottoms in cen-
ter contact.
Solder Attachment: Solder center conductor
to contact through the side access ports and
hole in center contact. Use a minimum amount
of solder for a full fillet joint. .020 (0.51) diam-
eter solder is recommended.
Crimp 50 Ohm connector contacts with 141-
0000-911 dieset in 144-900 tool frame. Crimp
75 Ohm connector contacts with 141-0000-924
dieset in 144-0000-900 tool frame.
