in a method for attaching a connector to a coaxial cable a solder preform is placed upon an end of an outer conductor of the cable . a connector body of the connector is seated upon an interface pedestal and the end of the outer conductor is inserted into a bore of the connector body against the interface pedestal . the outer conductor , the connector body and the interface pedestal contribute sidewalls to form a solder cavity , and the solder preform is heated . a seat may be applied to the interface pedestal to provide a thermal barrier and / or enhanced seal characteristics that are cost efficiently replaceable upon degradation .
