Technician exam question T0B04
Subelement T0, SAFETY· Group T0B
Which of the following is an important safety precaution to observe when putting up an antenna tower?
- A.Wear a ground strap connected to your wrist at all times
- B.Insulate the base of the tower to avoid lightning strikes
- C.Look for and stay clear of any overhead electrical wires (correct answer)
- D.All these choices are correct
WhyAn important safety precaution when putting up an antenna tower is looking for and staying clear of any overhead electrical wires. Overhead power lines near a tower site pose a severe, sometimes lethal risk if an antenna, mast section, or even a length of wire being raised makes contact with them, so identifying and staying well clear of them is essential, answer C. A wrist-worn ground strap (A) is an electronics anti-static precaution, unrelated to tower safety, and insulating a tower's base (B) doesn't meaningfully protect against a direct lightning strike, so D, which depends on both of those being valid precautions, is also wrong.
