4.3 System Cables
Make sure of the following before installing system cables.
1. All cables need to be well clamped and protected from physical damage and exposure to heat and
humidity.
2. Don't use any acutely bent cable.
3. Use watertight glands or swan neck tubes on exposed bulkheads or deck heads where the cable passes
through.
4. For installing cables longer than the recommended length, consult with Intellian Technologies rst.
4.3.1 RF Cable (Connecting ADU - BDU)
Due to the signal losses across the length of the RF coax on L-Band, Intellian recommends the following
50 coax cable types for standard system installations. Check the instructions from the cable supplier.
The table below shows the recommended cable types and maximum cable lengths for the antenna system.
