Installing Antennas
Note Before you install the Cisco 819 ISR on a table, wall, or DIN rail, install the antennas on the front panel.
It is difficult to install the antennas after the router is installed.
Orient the antennas. For optimum wireless performance, the antennas should be perpendicular with
respect to the floor.
If the router is being mounted on a desk, orient the antennas straight up.
To attach the radio antennas to your wireless router, follow these steps:
Step 1 Manually screw the antenna tight to the TNC connectors on the back of the router. (See Figure 2-2.)
