Installing Antennas

The Cisco 890 series wireless routers have three reverse-polarity threaded Neill-Concelman (RP-TNC)
connectors on the back panel. The antennas that are shipped with the router are dual-band 2.4-GHz to
5-GHz omnidirectional dipole antennas.
Warning Statement 372—All wireless LAN products in the 5.2/5.3GHz band cannot be used outdoors. Use the
product only indoors.

the back panel. It is difficult to attach the antennas after the router is installed.
