What defines the minimum height for antennas attached to an electric service mast in relation to power conductors?

The minimum height requirement for antennas attached to an electric service mast in relation to power conductors is indeed 36 inches. This guideline is in place to ensure safety and prevent any potential electrical hazards.

Maintaining a minimum distance of 36 inches between antennas and power conductors helps reduce the risk of accidental contact, which could lead to serious injury or electrical shock. It also aids in minimizing interference with the electrical service and maintaining proper clearance in accordance with local codes and safety standards. This distance allows for safe operation and maintenance of both the antenna system and the power lines, providing sufficient clearance in the event of movement caused by wind or other environmental factors.

The other height options do not meet the safety standards established for clearances between antennas and power conductors. Thus, 36 inches is the appropriate and required minimum height to ensure compliance and safety.
