Which of the following is an important safety precaution to observe when putting up an antenna tower?
The correct answer is C: Look for and stay clear of any overhead electrical wires. An important safety precaution when putting up an antenna tower is to look for and stay clear of any overhead electrical wires. Contact with power lines can cause electrocution, serious injury, or death. Towers and antennas must be positioned so that if they fall, they cannot contact power lines. For amateur radio operators, this is the most critical safety consideration when installing towers. Understanding this helps prevent fatal accidents.
Exam Tip
Tower installation = stay clear of power lines. Think 'P'ower 'L'ines = 'P'otentially 'L'ethal. Contact with power lines can kill. Most critical safety consideration. Not about ground straps or insulating base.
Memory Aid
"Tower installation = stay clear of power lines. Think 'P'ower 'L'ines = 'P'otentially 'L'ethal. Most critical safety consideration - contact can kill. Always check for overhead wires before installation."
Real-World Application
You're installing a tower near power lines. You carefully measure distances and position the tower so that even if it falls in any direction, it cannot contact the power lines. You maintain at least 10 feet clearance (more is better). Contact with power lines during installation or if the tower falls would be fatal.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Ground straps on wrists aren't used for tower installation - that's for static electricity protection in electronics work, not tower safety.
Option B: Incorrect. Insulating the tower base would prevent proper grounding, which is essential for lightning protection. Towers must be grounded, not insulated.
Option D: Incorrect. Since A and B are not correct, 'all of the above' cannot be correct. Only staying clear of power lines is the critical safety precaution.
