Which of the following establishes grounding requirements for an amateur radio tower or antenna?
The correct answer is B: Local electrical codes. Local electrical codes establish grounding requirements for amateur radio towers or antennas. While FCC rules govern radio operation, electrical safety and grounding are regulated by local building and electrical codes. These codes specify ground rod depth, bonding requirements, conductor sizes, and other safety standards. For amateur radio operators, compliance with local codes is required and ensures safe installations. Understanding this helps when planning tower installations.
Exam Tip
Tower grounding requirements = local electrical codes. Think 'L'ocal 'C'odes = 'L'egal 'C'ompliance. Local building/electrical codes establish grounding requirements. FCC rules are for radio operation, not electrical safety.
Memory Aid
"Tower grounding = local electrical codes. Think 'L'ocal 'C'odes = 'L'egal 'C'ompliance. Local building/electrical codes establish grounding requirements. Must comply with local codes for safety and legality."
Real-World Application
You're installing a tower and need to know ground rod requirements. You check your local electrical code, which specifies 8-foot ground rods, minimum conductor sizes, and bonding requirements. These local codes are the legal requirements you must follow. FCC rules don't specify electrical grounding - that's a local code matter.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. FCC Part 97 rules govern radio operation, not electrical grounding requirements. Grounding is an electrical safety matter, not an FCC radio matter.
Option C: Incorrect. FAA tower lighting regulations are for aviation safety (tower visibility), not electrical grounding. Different purpose.
Option D: Incorrect. UL recommended practices are guidelines, not legal requirements. Local codes are the legal requirements that must be followed.
