What distance should antenna and lead-in conductors be kept from other open wiring?

The correct distance that antenna and lead-in conductors should be maintained from other open wiring is 2 inches (50mm). This requirement is grounded in the National Electrical Code (NEC) guidelines, which are aimed at reducing the risk of electrical interference and ensuring safety during operation.

Maintaining a distance of 2 inches helps prevent issues related to electromagnetic interference between different types of conductors, which could lead to signal degradation or unintended coupling. The spacing ensures that the antenna and lead-in conductors can operate effectively without negatively impacting other electrical installations in proximity.

Furthermore, this 2-inch clearance aligns with common industry practices for maintaining safe and reliable wiring systems in both residential and commercial applications. It is crucial for compliance with the NEC to follow these recommendations to facilitate safety and functionality.
