Power Adapter Mobile Donor Antenna*
Server Antenna*

Attach the Donor Antenna and Server Antenna to the Main Unit.
Note: Adding a drip loop to the Donor Antenna cable is crucial as
it prevents water from owing down the cable and damaging the
Main Unit’s electronic equipment.
Using the provided M3 screw, attach one end of the ground cable
to the Main Unit and the other end to the chassis of the
automobile or boat.
Using the provided M3 screw, attach one end of the ground cable
to the Main Unit and the other end to the chassis of the
automobile or boat.
Find a suitable location to securely mount the Main Unit. When
installed, the Main Unit should have airow and be in a
position that doesn’t contact other objects. Make sure the
location provides enough distance for all the cables to connect.
It’s best to ensure all cables reach desired locations BEFORE
mounting the device.
Mount your Donor Antenna on the exterior and towards the rear
of your automobile or boat, depending on the design and type
of vehicle. Make sure you consider the cable connection to the
Main Unit with your location choice. Note: For best performance,
ensure there is 50 cm of metal around the base of the antenna.
Quick Installation IMPORTANT: Your CEL-FI GO G41 is electronic equipment. The CEL-FI GO G41
must be kept indoors and in a dry, cool, well ventilated area.
