The combo antenna is provided with three flexible coaxial cables
coming out of the antenna bottom side (two threads for internal and GPS
are used). Two 12ft coaxial cables are also provided in order to connect
between the internal and GPS threads and the modem connectors.
Connect the internal cable connector to the WWAN2 DIV port on the VSM
connector panel.
Connect the GPS cable connector to the GPS port on the VSM connector panel.
Be sure to connect the RG-174 cable to the GPS connector.
Form a service loop to contain any excess cable length. It is required to form the
service loop for the flexible cables coming out of the antenna bottom near the cable
exit. These service loops should have a minimum bend radius of 1" (2.54 cm). If
needed, form a second service loop for the excess length of the jumper cables near
the VSM with minimum bend radius of 3" (7.63 cm). Use plastic cable ties to
secure the cable.
