INSTALLING THE ANTENNA
System Cables
Before installing the system cables, you need to take the following points into
consideration.
•
All cables need to be well clamped and protected from physical damage and
exposure to heat and humidity.
•
A cable with an acute bend is not allowed.
•
Wherever a cable passes through an exposed bulkhead or deck head, a
watertight gland or swan neck tube should be used.
