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 300mm (12 inches) from an ADF
antenna cable.
 Keep the cable run as short as possible.
