Question E1B07:
[97.15] To what type of regulations does PRB-1 apply?  

Choices:  
A: Homeowners associations  
B: FAA tower height limits  
C: State and local zoning  
D: Use of wireless devices in vehicles    

Correct Answer is  C: State and local zoning  

PRB-1 is the FCC’s policy (codified in 47 CFR §97.15(b)) that requires state and local governments to reasonably accommodate amateur radio communications and to apply the minimum practicable regulation to antenna structures.

Why C (State and local zoning) is correct:
- PRB-1 preempts overly restrictive state and local zoning/land-use ordinances affecting amateur antennas and towers.
- It requires “reasonable accommodation” and “minimum practicable regulation” by governmental (not private) authorities.

Why the others are incorrect:
- A: Homeowners associations — PRB-1 does not apply to private land-use restrictions such as CC&Rs or HOA rules. Those are private agreements, not governmental regulations.
- B: FAA tower height limits — FAA/FCC structure rules (e.g., 14 CFR Part 77, FCC Part 17) are federal aviation/safety regulations; PRB-1 does not change or override them.
- D: Use of wireless devices in vehicles — Vehicle and mobile device use laws are unrelated; PRB-1 addresses fixed antenna structures and local zoning, not operating while driving.

Rules of thumb:
- PRB-1 scope: Governmental zoning/land-use only; no preemption of private covenants (HOAs/CC&Rs).
- “Reasonable accommodation” means localities can regulate for safety/aesthetics but should not effectively prohibit amateur service.
- FAA/FCC notification/marking often triggers at heights > 200 ft (about 61 m) AGL or near airports; PRB-1 does not waive these requirements.
