Why should you avoid attaching an antenna to a utility pole?

C
Answer
Electrical, RF, and mechanical safety
Type
A
The antenna will not work properly because of induced voltages
B
The antenna may unbalance the power transformer, causing power fluctuations
C
The antenna could contact high-voltage power lines
D
All these choices are correct

Answer Notes

Safety is always the top priority in amateur radio. Utility poles carry high-voltage power lines that can be lethal if accidentally contacted. If an antenna, feedline, or guy wire were to touch these lines during installation or a storm, it could cause severe injury or death. While some might worry about induced voltages or equipment performance, the primary and most critical reason to avoid utility poles is the extreme electrocution hazard. Distractors like unbalancing the power transformer are completely inaccurate, as a mere antenna wire will not unbalance a utility-scale transformer. Therefore, 'All these choices are correct' is incorrect because only the physical contact hazard is the true reason.
