Which of the following is an important safety precaution to observe when putting up an antenna tower?
Wear a ground strap connected to your wrist at all times
Insulate the base of the tower to avoid lightning strikes
Look for and stay clear of any overhead electrical wires✓پاسخ درست
All these choices are correct
توضیح
Contact with an overhead power line during an antenna or tower installation can be immediately fatal, so the location of any power lines must be identified and the work kept well clear of them. A wrist ground strap is for static-sensitive electronics, and insulating the tower base does not prevent lightning strikes.
