This ground block designed to provide a signal ground when running coax cable, rated at 3 Ghz of signal capacity. These blocks will intercept a lightning signal or power spikes carried by coaxial cables and harmlessly redirect the electricity to the ground, protecting your TV, VCR, Satellite, Computer, etc. Works with standard 75 ohm cable or coax cable.
The internal components of these ground blocks are much different from a standard frequency VHF/UHF ground block. The center coax conductor indexes into a close-tollerance tube that is resilient (spring) brass and is 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.
