Lightning Protector

Quarter wave stub technology is based on a three-port coaxial device with N female connectors. When lightning strikes, current is instantaneously diverted to the ground through a short circuit mechanism in the stub. The advantages of this technology are no maintenance required and the lowest residual voltage passes through to the equipment.
