Install Donor Antenna
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.
Install the Server Antenna
Install the Server Antenna in the cabin/deck towards the front of the
vehicle where coverage is needed. Make sure to mount the Server Antenna
horizontally.
Note: The Donor Antenna should be separated/isolated as far away as
possible from the Server Antenna , greater separation provides the best
performance.
Select the Main Unit Location
Find a suitable location to securely mount the Main Unit. When 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.

Note: Adding a drip loop to the Donor Antenna cable is crucial as it
prevents water from flowing down the cable and damaging the Main Unit’s
electronic equipment.

Unit and the other end to the chassis of the automobile or boat.
