What is the minimum safe distance from a power line to allow when installing an antenna?

The minimum safe distance for installing an antenna in relation to power lines is critically important for ensuring safety and compliance with regulations. The correct answer emphasizes the necessity of maintaining a safe distance, specifically stating that if the antenna were to fall, there should be enough clearance to ensure that no part of the antenna comes within 10 feet of the power wires.

This guideline is based on safety standards that aim to prevent accidental contact with electrical conductors, which can lead to severe electrical hazards, including shock or fire. The 10-foot clearance provides a significant safety margin, accounting for the potential swing or droop of the antenna due to wind or other factors.

Other choices while they may offer methods for determining distances, do not specifically address the critical aspect of fall safety or the recommended clearance from power lines. For example, some may consider the height of the power line or operating frequency, but these factors do not necessarily take into account the practical considerations of an antenna structure's behavior during adverse conditions. Thus, maintaining a defined distance based on the potential for the antenna to collapse is the most prudent approach.
