Question T0B09
From subelement T0 - T0B
Why should you avoid attaching an antenna to a utility pole?
Why is this correct?
The correct answer is C because utility poles carry high-voltage power lines that can energize your entire antenna system if contact occurs, creating deadly electrical hazards. Options A and B are incorrect—induced voltages and 60 Hz interference don't prevent antenna function or significantly affect SWR. The primary safety concern is electrocution risk from high-voltage contact, not performance issues.
Memory tip
When evaluating antenna safety questions, focus on life-threatening hazards over performance issues. High voltage always trumps RF performance concerns in safety priorities. This pattern appears across many amateur radio safety scenarios—direct electrical contact dangers take precedence over operational considerations.

Utility poles often carry multiple electrical circuits at different voltage levels, including distribution lines that can exceed 10,000 volts. Per Part 97 installation requirements, amateur stations must comply with electrical safety codes. A fallen antenna contacting these lines creates a ground fault that can energize your coaxial shield, tower, and station equipment, potentially electrifying everything connected to your amateur installation.

Why do you think amateur radio regulations emphasize electrical safety over antenna performance when it comes to installation requirements?
