Antenna
Connect cellular antenna to the router to main (ANT) SMA connector.
Only run the router with a 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 connectors is 0.9 Nm.
