Cables
Four types of cables used for standard installation are introduced in the subsections
below. For cables that run longer than Intellian’s recommendations, please consult
Intellian Technologies.
• 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.
Cable with an acute bend are not allowed.
3.
Where a cable passes through an exposed bulkhead or deck head, a
watertight gland or swan neck tube should be used.
• Power Cables
The cable sizes recommended in the following table are the input power cable size
for standard system installation.

Note : The power cable in the package is 10 meter in length.
• RF Cables (Customer Furnished)
Due to the voltage 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 200 meters, please consult Intellian
Technologies.
