ARRL Technician Practice Exam

What entity establishes grounding requirements for an amateur radio tower or antenna?

1. Federal Communications Commission (FCC)

2. Local electrical codes

3. National Electrical Code (NEC)

4. American Radio Relay League (ARRL)

The correct answer is: Local electrical codes

The grounding requirements for an amateur radio tower or antenna are indeed established by local electrical codes. These codes are formulated by local jurisdictions and can vary significantly based on geographic location and municipal regulations. Local electrical codes take into account specific factors such as soil type, climate, and local building practices to ensure safety and effectiveness in grounding installations. While the National Electrical Code (NEC) provides a comprehensive set of standards that many local codes adopt or reference, it is ultimately the local authority that enforces these guidelines and regulations specific to ground installations. Therefore, compliance with local electrical codes is essential for anyone setting up amateur radio equipment, as these codes serve as the definitive authority in ensuring that installations are safe and are in line with local practices and regulations. The Federal Communications Commission (FCC) primarily regulates communications in the US, including amateur radio operations, but does not set specific requirements for physical installations such as grounding. The American Radio Relay League (ARRL) provides guidance and recommendations to amateur radio operators, but they do not have the authority to establish binding regulations regarding grounding or other electrical safety standards.
