Which of the following is an important safety precaution to observe when putting up an antenna tower?

An important safety precaution when erecting an antenna tower is to look for and stay clear of any overhead electrical wires. This precaution is critical because overhead power lines pose a serious risk of electrical shock, electrocution, and other hazards. Maintaining a safe distance from these wires is essential to prevent accidental contact during the installation process, which often involves lifting and positioning materials that may reach into the vicinity of the power lines.

While wearing a ground strap can help prevent static electricity buildup, and insulating the base of the tower is relevant for minimizing lightning hazards, the most immediate and tangible risk comes from overhead wires. Ensuring a clear working area around the installation site is therefore the most crucial safety measure in this context.
