INSTALLING THE ANTENNA
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 a tight bend radius should be avoid.
3. Where a cable passes through an exposed bulkhead or deck head, a watertight
gland or swan neck tube should be used.
RF Cable (Customer supplied)
Due to the signal losses across the length of the RF coax on L-Band, Intellian
recommends the following 75 ohm coax cable types for standard system
installations. For cables that run longer than 100 meters, please consult Intellian
Technologies.
