Planning Installation
Preparing System Cables
Before installing the system cables, you need to take the following points into consideration.
1. All cables need to be well clamped and protected from physical damage and exposure to heat and humidity.
2. A cable with an acute bend should be avoided.
3. Wherever a cable passes through an exposed bulkhead or deck head, a watertight gland or swan neck
tube should be used.
For cables that run longer than Intellian's recommendations, please consult Intellian Technologies.

RF Cable (Customer Supplied)
Due to the signal losses across the length of the RF coax on L-Band, Intellian recommends the following 50
ohm coax cable types for standard system installations. For cables that run longer than 120 meters (except
LMR600 coaxial cable type), please consult Intellian Technologies.
* The Maximum DC Resistance of RF Cable is 0.8 Ohm.
* Tightening Torque Value: N Type Connector, 1.5 N-m
