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

The minimum safe distance when installing an antenna in relation to power lines is determined by ensuring that, in the event of a mishap such as the antenna falling, its closest point is at least 10 feet away from the power wires. This distance is crucial for safety, as it helps to prevent any potential electric shock hazards due to unintended contact with the power lines. Power lines carry high voltages, and even brief contact can lead to serious injury or fatalities.

Maintaining a 10-foot clearance ensures a buffer zone that accounts for various potential scenarios during installations or maintenance work, as well as unexpected antenna movement caused by environmental factors such as wind. This precaution aligns with safety guidelines commonly referenced in amateur radio practices, emphasizing the importance of grounding and installation procedures when working near utility infrastructure.
