What is the minimum safe distance from a power line when installing an antenna?

5 feet
10 feet
15 feet
20 feet

The correct answer is: 10 feet

The minimum safe distance from a power line when installing an antenna is 10 feet. This guideline is critical to ensure the safety of personnel working near power lines. Staying at least this distance helps to mitigate the risk of electrical shock or other accidents associated with contact or near-contact with energized wires. When working with antennas, various factors such as the antenna height and the type of installation can affect safety. However, the 10-foot rule serves as a practical baseline designed to protect individuals from potential hazards that can occur if the antenna or any supporting structure comes too close to the power lines. It's also important to consult local regulations or guidelines, as some areas may have more stringent requirements for safe distances from power lines to enhance safety further.
