Electrical receptacle for coaxial cable

An electrical receptacle, comprising,

• a conductive body with an inner surface defining an inner receiving area;
• a dielectric assembly received in the inner receiving area of the conductive body, the dielectric assembly comprising an entry dielectric portion, a distal support dielectric portion opposite the entry dielectric portion, and a reduced-diameter dielectric portion therebetween;
• an air region defined between the inner surface of the conductive body and the reduced-diameter dielectric portion of the dielectric assembly, the air region being at least half of the inner receiving area of the conductive body;
• an outer conductor coupled to the conductive body and receiving at least part of the entry dielectric portion;
• and
• an inner contact having a mating interface end for receiving a corresponding mating contact, a solder end for engaging a printed circuit board, and an inner through bore therebetween, the mating interface end being received in the reduced-diameter dielectric portion,
• wherein the dielectric assembly positions the inner contact along a central longitudinal axis of the conductive body.
