Installing Antennas
Cisco Aironet 5-GHz 8-dBi Omnidirectional Antenna (AIR-ANT5180V-N)
The Cisco Aironet 5-GHz 8-dBi Omnidirectional Antenna is designed for outdoor use with Cisco
Aironet Outdoor Access Points with radios operating in the 5-GHz frequency band. This antenna has
8-dBi gain in the 5-GHz frequency band.
For detailed information on this antenna, refer to the document
Cisco Aironet 8-dBi Omnidirectional
Antenna (AIR-ANT5180V-N)
. Follow all safety precautions when installing the antennas, for information
on safety, refer to
“Safety Precautions when Installing Antennas” section on page 2-18

Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct
contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning
Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over
voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed
according to these mounting instructions balances the voltage potential, thus preventing inductive
interference to parallel signal lines within the protected system.
