The center coax conductor indexes into a close-tolerance tube that is resilient (spring) brass and gold-plated. The close center-tube tolerance assures a tight connection, and the gold plating ensures a strong electrical connection.
Overall performance is greatly improved over standard designs. Internally, the center conductor tube is insulated from the inner design of the barrel by a maximum air gap which results in much less RF loss. Insertion loss is extremely low. It is rated at 3 GHz. This in-line spice connector is intended for outdoor use. Rubber weather seals on each side provide an added layer of moisture resistance.
