3. Router Design
3.9.3 Antenna Connector ANT, DIV and WiFi
The main and diversity antennas are connected to the router using the SMA connector on the front
panel. There is also an R-SMA antenna connector available, through which an additional antenna can be
connected, if the router is equipped with a WiFi module.
The ANT connector is used to First, connect the main antenna to the router. To connect the diversity
antenna, the second antenna connector DIV is used. An R-SMA connector named WiFi is designed for the
connection of a WiFi antenna (available only for versions with a WiFi module).
The router can not operate without a main antenna connected through the port marked as ANT !
The DIV celullar antenna is required for the MIMO DL functionality.
An SMA connector is used for the connection of the antenna. The antenna is connected by screwing this
antenna to the SMA connector on the router's front panel (see the figure below). Recommended tightening
moment is 0.9 Nm.
A diversity antenna improves the radio capability of the router at low signal strength.
