Aerial coax cables must have a minimum separation distance of what from electric power conductors?

The minimum separation distance for aerial coax cables from electric power conductors is established to ensure safety and minimize the risk of interference. A separation of 4 inches is considered the standard because it reduces the chance of electrical arcing and maintains the integrity of the coaxial cable's signal. This distance also acknowledges the heat and electromagnetic fields generated by electric conductors, which can impact coax cable performance if too close.

While the other options suggest greater distances, the standardization at 4 inches balances safety and practicality, allowing for efficient installation without unnecessary spacing that could complicate the infrastructure. This regulation reflects best practices in telecommunications and electrical safety to ensure that both systems can coexist without detrimental effects.
