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

When installing an antenna, safety is the primary concern, especially regarding nearby power lines. If a mast or tower were to collapse, you must ensure that no part of the structure or the antenna itself can come within 10 feet of a power line. This prevents deadly electrical arcs and direct physical contact. Distractors like using a half-wavelength distance or calculating a multiplier based on power line height are completely arbitrary and do not account for the physical radius of a falling antenna. The 10-foot clearance rule provides a guaranteed buffer zone against high-voltage arcing even in a worst-case scenario.
