* All range estimations are based on an external antenna associating with an integrated Intel Centrino client
under ideal conditions. The distances referenced here are approximations and should be used for estimation
purposes only.
** The cable provided on noted antennas meets UL 2043 certification for plenum rating requirements set by
local fire codes and supports installation in environmental air spaces such as areas above suspended ceilings.
*** 5 GHz antennas are denoted by either a blue dot on the radome or blue marker on the cable near the
connector.
**** Best suited for use on the Cisco Aironet 1250 Series Access Point but can also be used on other access
points with RP-TNC connectors.
Cisco Dual Band Antenna for 2.4 GHz and 5 GHz Access Points
Cisco offers a dual band antenna, or a radome which has both 2.4 GHz and 5 GHz elements in
one low profile package. The antenna has 4 cables, two for 2.4 GHz and 2 for 5 GHz, color coded
to prevent any accidental connections. Easy to install and lightweight, this antenna is ideal for
indoor wall or ceiling mount applications (Table 3).
