Attach Server and Donor Antennas
Server Port
Find a suitable location to securely mount the Main Unit. When installed, the Main Unit should have airflow 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.
