Direct-solder attachment is the most efficient method of attaching
semi-rigid cable. The cable is stripped and the connector contact
soldered to the cable conductor. (Some SMA connectors do not have
a separate contact; for these types, the conductor of .141"
semi-rigid cable extends through the connector insulator and is
used as the contact.)
The prepared cable is inserted into the body assembly, and the
jacket (outer conductor) of the cable is soldered to tail of the
Captive contacts (as shown) are strongly recommended for connectors
used with semi-rigid cable, to prevent movement from cable flexure
or temperature changes after assembly.
