What is the required vertical clearance for overhead coax cables above roofs?

The required vertical clearance for overhead coax cables above roofs is typically set at 8 feet. This clearance is important to ensure safety and accessibility for any maintenance equipment and personnel. It also helps to minimize the risk of damage to the cables from environmental factors, such as snow accumulation or roof debris. Maintaining this standard height above roofs allows for clear passage and reduces the likelihood of service interruptions or issues related to cable sagging.

Other options, while varying in height, do not meet the standard requirement established for overhead coax cables in terms of safety and operational effectiveness.
