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.
