Protects signal boosters from lightning strikes? Prevent a lightning strike from destroying your electrical system. The 50 ohm Arrester with N Male to Female Connectors can be installed to prevent expensive damage from incapacitating your circuitry. The arrestor safeguards your amplifier and boosted devices from power surges caused by lightning strikes to antennas mounted outside coaxial lightning arrester should be installed as close a possible to the equipment to be protected, often at the point where the coax cable enters the building.
