Which of the following establishes grounding requirements for an amateur radio tower or antenna?

• A. International radio regulations
• B. Local electrical codes
• C. Manufacturer guidelines
• D. National weather standards

Answer: (B)

The establishment of grounding requirements for an amateur radio tower or antenna primarily falls under local electrical codes. These codes are put in place to ensure the safety and proper functioning of electrical installations, including dealing with issues related to lightning protection and minimizing electrical hazards. Local electrical codes address specifics that can vary by region, taking into account the environment, type of buildings, and the particular demands of local infrastructure.

While manufacturer guidelines can provide important information about the setup and safety of specific equipment, they do not typically encompass the comprehensive legal and safety directives contained in local electrical codes. International radio regulations do not specifically address grounding for amateur installations either, focusing instead on broader issues of radio frequency usage and compliance across nations. National weather standards might touch on weather-related safety protocols but do not directly provide requirements for grounding tower installations.

This makes local electrical codes the most relevant authority in defining the necessary safety measures and practices for grounding an amateur radio tower or antenna, thereby ensuring compliance and protection.
