Bronze is a code compliant conductor material for radio antenna grounding electrode conductors. True or False?

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

Answer: (A)

Grounding electrode conductors can be made from copper or from other approved conductive materials. Bronze is a copper alloy with good corrosion resistance, and the NEC allows conductors beyond pure copper if they’re an approved material for that use. Because bronze is conductive and durable in outdoor environments, it qualifies as a code-compliant choice for a radio antenna grounding electrode conductor. When using bronze, size and installation must still meet the same grounding requirements (proper sizing for the system and secure bonding) as with copper.
