What is the minimum separation required between coaxial cables in a CATV system and lighting conductors?

In a CATV (Community Access Television) system, the minimum separation required between coaxial cables and lighting conductors is essential for ensuring safety and maintaining the integrity of the signals being transmitted. A separation of 6 feet is prescribed to prevent electromagnetic interference that could affect the performance of the coaxial cables and also to safeguard against inductive coupling, which can occur in the presence of high voltage lighting conductors.

The 6-foot separation distance helps to mitigate any potential hazards that could arise from lightning strikes or electrical faults in nearby lighting systems impacting the coaxial cable lines. This distance is a commonly accepted standard in industry regulations to help ensure safe installation practices. By adhering to this requirement, technicians can enhance the reliability of the CATV system while also protecting both the equipment and individuals from electrical hazards.

This standard reflects best practices in low voltage special systems installation, highlighting the importance of maintaining appropriate distances between different types of conductors to optimize performance and safety.
