Antennas

The Cisco 819 3G routers provide two standard panel-mount TNC connectors to support the 3G antenna and the diversity and GPS external antenna. The main antenna is used for the primary 3G antenna. The second can be used as a diversity receive only 3G antenna or GPS antenna that does not require power supply from the router.

The Cisco 819 4G routers provide two standard panel-mount TNC connectors on the router front panel for the main and diversity antennas. The main antenna connector is used for the primary 4G antenna. The second antenna connector can be used as a diversity receive only 4G antenna. An SMA connector for active GPS antenna is also available on the front panel of the router.

The Cisco 819HGW and Cisco 819HWD ISRs also support Cisco WiFi external antennas. See the “Supported Cisco Antennas and Cables”section on page 1-19for more information.
