Cellular Antennas
Main (ANT) and diversity (DIV) antennas can be connected to the router using the SMA
connectors located on the front panel.
Do not run the router without connected cellular antenna connected to the main antenna
connector as the energy from the transmission is effectively reflected by the open end
and can damage the equipment.
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.
The diversity antenna improves the radio capability of the router at low signal strength.
