Symmetricom 58538A Overview

Lightning can damage GPS system components and receiving equipment, even without a direct hit. This can result in costly repairs and critical interruption of service. The 58538A Lightning Arrestor and 58539A GPS L1 Lightning Arrestor are designed to work in conjunction with a lowresistance, low-inductance ground to protect your GPS receiver and elements of the antenna system from lightning discharges and field-induced electrical surges.

The 58538A is a small, waterproof unit designed to operate in the communications band up to 2.5 GHz, and to take much of the energy out of a nearby lightning strike. This unit is typically installed in a grounding panel where the antenna cable enters the building. The 58538A will protect receiving equipment only, and must be used in conjunction with the 58539A.
