5.6 Antenna Connection
Caution: Antennas 1 & 2 Tx/Rx must be connected and attached before Air4G-
W24 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-W24 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-W24 Tx/Rx port must be connected to a “+45 degree”
port in the quad port antenna and another Air4G-W24 Tx/Rx port must be connected to a “-45
degree” port in the quad port antenna. The Air4G-W24 Rx ports need to be connected to the
remaining connectors on the antenna side. Two (2) examples are displayed below.
