Cisco 3G Lightning Arrestor

The Cisco 3G-ACC-LA provides a level of safety protection to the user as well as to wireless equipment by shunting to ground over-voltage transients induced into outdoor antennas and cables. These transients, in mild cases can produce interfering signals in a wireless system, and in extreme cases, can be dangerous and destructive.

Overvoltage transients can be created through lightning static discharges, switch processes, direct contact with power lines, or through earth currents. The Cisco 3G-ACC-OUT-LA Lightning Arrestor limits the amplitude and duration of disturbing interference voltages and improves the overvoltage resistance of in-line equipment, systems, and components. A lightning arrestor installed according to these mounting instructions balances the voltage potential, thus providing safety and preventing inductive interference to parallel signal lines within the protected system.

The Cisco 3G-ACC-OUT-LA Lightning Arrestor is designed for use with Cisco 3G wireless devices and Cisco 4G wireless devices, and antennas and cables that use standard TNC connectors.
