Which statement about bronze as a conductor material for radio antenna grounding electrode conductor is correct?

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Bronze is a copper-based alloy with good corrosion resistance, which makes it suitable for outdoor grounding connections like a radio antenna grounding electrode conductor. The NEC allows conductor materials beyond pure copper as long as they have adequate conductivity, corrosion resistance, and are properly installed and sized. Bronze’s conductivity is lower than pure copper but still adequate when the conductor is sized per the code and connections are made with compatible hardware to prevent galvanic issues. Therefore, bronze can be used for a grounding electrode conductor, so the statement is true.
