What is the minimum required clearance between a receiving antenna and a 250-volt line not insulated?

The minimum required clearance between a receiving antenna and a 250-volt line that is not insulated must take into account safety standards to prevent electrical hazards. This clearance is necessary to mitigate the risk of electrical shock or interference, ensuring that there are no unsafe conditions created by proximity to conducting wires.

The National Electrical Code (NEC) and other safety guidelines specify that for lines carrying such voltage, a minimum clearance of 2 feet is typically regarded as a safe distance. This helps to ensure that any potential electrical arcs or accidental contact with the antenna are minimized, safeguarding both the equipment and individuals nearby.

Given these considerations, the requirement of a 2-foot clearance reflects both practical safety measures and regulatory standards pertaining to electrical installations. This ensures that the antenna operates effectively while maintaining safety for people and equipment in the vicinity.
