SkyView System Installation Guide - Revision R 11-13
The following table is a guide to the maximum usable lengths of some common cable types.
Actual cable loss varies between manufacturers, there are many variants, and the table is
therefore based on typical data. Use it as a guide only and refer to the manufacturer’s data
sheet for your specific chosen cable for accurate values.

When routing the cable, ensure that you:
 Route the cable away from sources of heat.
 Route the cable away from potential interference sources such as ignition wiring, 400Hz
generators, fluorescent lighting and electric motors.
 Allow a minimum separation of 300 mm (12 inches) from an ADF antenna cable.
 Keep the cable run as short as possible.
 Avoid routing the cable round tight bends.
 Avoid kinking the cable even temporarily during installation.
 Secure the cable so that it cannot interfere with other systems.
