Deep Dive: G1B01
The correct answer is C: 200 feet. The maximum height above ground for an antenna structure not near a public use airport without requiring notification to the FAA and registration with the FCC is 200 feet. Structures above 200 feet require FAA notification and FCC registration (Form 854) for aviation safety. For amateur radio operators, understanding this height limit helps when planning antenna installations. Structures near airports have lower limits and additional requirements.
Why Other Answers Are Wrong
Option A (50 feet): Incorrect. 50 feet is well below the limit - no notification is needed at this height unless near an airport. Option B (100 feet): Incorrect. 100 feet is below the 200-foot limit - no FAA notification or FCC registration is required. Option D (250 feet): Incorrect. 250 feet exceeds the 200-foot limit - FAA notification and FCC registration would be required.
Exam Tip
Antenna height limit = 200 feet without FAA/FCC. Think '2'00 feet = '2'00-foot 'L'imit. Structures above 200 feet require FAA notification and FCC registration. Below 200 feet, no notification needed (unless near airport).
Memory Aid
Antenna height limit = 200 feet. Think '2'00 feet = '2'00-foot 'L'imit. Structures above 200 feet require FAA notification and FCC registration. Below 200 feet, no notification needed (unless near airport).
Real-World Example
You're installing a 150-foot tower. Since it's below 200 feet and not near an airport, you don't need to notify the FAA or register with the FCC. If you were installing a 250-foot tower, you'd need to file with both the FAA (for aviation safety) and the FCC (Form 854 registration) before construction.
