Indoor Connector F81 Barrel High Frequency

The internal components of this fitting are much different from a standard VHF/UHF barrel connector. 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, the gold plating assures a good electrical connection, and the overall performance is greatly improved over standard designs. Internally, the center conductor tube is insulated from the inner skin of the barrel by a maximum air gap which results in much less RF loss. Insertion loss is extremely low and not really necessary to consider in complex systems. They come 50 barrels per package. DIRECTV approved Internal components designed for high-frequency Gold plated center conductor assures minimum RF loss & strong electrical connections Resilient internal metals for dependable repeated insertion connections Easily used in wall plates using the included washer and nut Minimal insertion loss indoor use only.
