In the context of coaxial cables used in outdoor applications, maintaining a proper separation from lighting conductors is crucial for ensuring both safety and signal integrity. The correct minimum distance for separation is 4 inches. This guideline is derived from standards that aim to prevent electromagnetic interference and potential damage to the coaxial cable from electrical surges that can occur in lighting conductors.

When coaxial cables are positioned too close to lighting conductors, they may pick up unwanted electrical noise, which can degrade the performance of the cable and the signals it transmits. Furthermore, the risk of voltage spikes caused by lightning or electrical faults increases with proximity to these conductors. By adhering to the specified 4-inch separation, the integrity of the coaxial cable's function can be upheld while also ensuring the safety of the installation.

This specific distance ensures compliance with industry regulations and helps protect against the risks associated with electrical interferences.
