Plain-language answer: Power lines can create noise and coupling, but the overriding issue is lethal contact or flashover risk: antennas, masts, guys, and falling parts must stay far away.
Why it matters in the complete station
A conductive antenna does not need to touch a line to become dangerous under all conditions. Wind, assembly, collapse, and carrying position must be included in clearance planning.
What to do in the field
Choose another site whenever any part could reach a line. Treat suspected utility noise as a separate issue to document and report safely.
The common mistake
Working closer because the antenna is “only temporary” or the line appears insulated.
Safety boundary
Stop work around power lines, lightning, unstable supports, unsafe wind or ice, damaged components, or uncontrolled public access. Current product guides, component ratings, site rules, electrical code, license conditions, and RF-exposure requirements control the final installation.
