Under what conditions are state and local governments permitted to regulate amateur radio antenna structures?
The correct answer is D: Amateur Service communications must be reasonably accommodated, and regulations must constitute the minimum practical to accommodate a legitimate purpose of the state or local entity. Under the conditions for state and local governments to regulate amateur radio antenna structures, amateur communications must be reasonably accommodated, and regulations must be the minimum practical to serve a legitimate government purpose. This is the PRB-1 standard - governments can regulate but must reasonably accommodate amateurs and use minimum necessary regulation. For amateur radio operators, this provides protection while allowing necessary regulation.
Exam Tip
State/local regulation = reasonable accommodation, minimum practical. Think 'R'easonable 'A'ccommodation = 'R'equired 'A'nd minimum practical. PRB-1 standard: governments can regulate but must reasonably accommodate amateurs and use minimum necessary regulation.
Memory Aid
"State/local regulation = reasonable accommodation, minimum practical. Think 'R'easonable 'A'ccommodation = 'R'equired. PRB-1 standard: governments can regulate but must reasonably accommodate amateurs and use minimum practical regulation."
Real-World Application
Your local government wants to restrict antenna height to 35 feet. Under PRB-1, they can regulate, but they must reasonably accommodate your amateur radio operation and use the minimum practical restriction. If you can demonstrate that 35 feet prevents reasonable operation, they may need to allow a higher structure. The regulation must balance legitimate government interests with amateur radio needs.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. State and local governments can regulate antenna structures - FCC rules don't completely preempt local regulation. However, regulation must reasonably accommodate amateurs.
Option B: Incorrect. Governments can't regulate 'at any time to any extent' - they must reasonably accommodate amateurs and use minimum practical regulation.
Option C: Incorrect. The 50-foot/1000-foot visibility rule isn't the standard - the standard is reasonable accommodation and minimum practical regulation.
