5.8.1 External Duplexer to Air4G Connection
The following describes the RF connection between the Air4G (FDD variant) and the external
Duplexer:
Caution: Attach the appropriate cable to the antenna and hand-tighten. Torque
the N-Type connector to 6.2 - 9.7 in-lbs or 0.7 - 1.1 N-m using either a 19mm or
13/16” open end Torque wrench (depending on coupling type).

Note: The Duplexer antenna ports, on the top panel, are connected to a dual (2)
port antenna.
5.9 Antenna Connection
Caution: Tx Antennas must be connected and attached before Air4G is powered
on.
Caution: Attach the appropriate cable to the antenna and hand-tighten. Torque
the N-Type connector to 6.2 - 9.7 in-lbs or 0.7 - 1.1 N-m using either a 19mm or
13/16” open end Torque wrench (depending on coupling type).
Caution: Power down Air4G prior to disconnecting antenna.
The following describes the antenna connection:
Note: Some antennas are labeled 1, 2, 3, 4 and some are labeled ‘+’, ‘–‘, ‘+’, ‘–‘.
The quad port antenna has two dual slant antennas in it (meaning two +/-45 degree antennas) –
as such it has two “+45 degree” ports and two “-45 degree” ports.
To provide maximum efficiency one Air4G Tx/Rx port must be connected to a “+45 degree” port in
the quad port antenna and another Air4G Tx/Rx port must be connected to a “-45 degree” port in
