General precautions to avoid Triax problems
• Only use Triax cable (with three conductors).
• Ensure that all Triax connectors (camera, base station and extension cables) fit snugly into
each other.
• Verify that there is no interruption in all three conductors of the Triax cable before
deploying (including extension Triax cables).
• When using Triax connectors be sure to always make swift and firm connections to avoid
unintended fault conditions.
• Verify that there is no shortcircuit between the outer and inner shield or core.
