Why should you avoid attaching an antenna to a utility pole?
The antenna will not work properly because of induced voltages
The antenna may unbalance the power transformer, causing power fluctuations
The antenna could contact high-voltage power lines✓Richtige Antwort
All these choices are correct
Erklärung
Utility poles carry energised high-voltage conductors, and working at the pole or having an antenna shift or fall there can bring metal into contact with them. That contact is potentially fatal, which is reason enough regardless of any effect on antenna performance.
