In a method for attaching a connector to a coaxial cable a solder perform 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 perform 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.
