What is the minimum safe distance from a power line to allow when installing an antenna?
Add the height of the antenna to the height of the power line and multiply by a factor of 1.5
This answer is incorrect because multiplying the height of the antenna and power line by a factor of 1.5 does not directly relate to safe distance in terms of falling distance and potential electrical hazards.
The height of the power line above ground
This answer is incorrect because simply considering the height of the power line above ground does not account for scenarios where the antenna may fall and therefore does not ensure a safe distance.
1/2 wavelength at the operating frequency
This answer is incorrect because the distance referenced (1/2 wavelength at the operating frequency) is irrelevant to safety concerning power line proximity.
Enough so that if the antenna falls, no part of it can come closer than 10 feet to the power wires
This answer is correct because ensuring that the antenna, if it falls, does not come closer than 10 feet to power wires helps prevent electrical hazards and maintains a safe installation environment.

When it comes to installing antennas, safety is a paramount concern, especially when dealing with the proximity of power lines. The question addresses the importance of maintaining a safe distance from power lines to avoid any accidental contact which could lead to severe injuries or even fatalities. The minimum safe distance ensures that if the antenna were to fall or collapse, it would not come into contact or close proximity with power lines, thus preventing any electrical hazards.
The correct answer is to ensure that if the antenna falls, no part of it can come closer than 10 feet to the power wires. This guideline helps provide a significant safety margin: given that power lines can carry high voltages, maintaining a distance of at least 10 feet is critical to mitigate the risks of electrical shock or other related incidents. This question is foundational in amateur radio operations as it emphasizes the importance of planning and safety in antenna installations.
