IEC 60169-21:1985
Standardizes the interface and ratings of two versions of a medium size r.f. connector for use with flexible and semirigid cables. The connectors are recommended to be utilized in medium power and low reflection applications up to 11 GHz. The dielectric filled interface is especially beneficial in applications involving severe environmental exposure.
Both versions of this connector type are screw coupled versions of the Type C connector.

The two types are not intermateable. It is recommended to use only the type SC-B in new installations.
