Ham Radio General Class Practice Test

What is the maximum height of an antenna structure that does not require FAA notification, provided it's not at or near a public airport?

1. 50 feet

2. 100 feet

3. 200 feet

4. 300 feet

The correct answer is: 200 feet

The maximum height of an antenna structure that does not require FAA notification is 200 feet, provided that it is not situated at or near a public airport. This regulation is in place to ensure that antennas do not interfere with aviation safety without undue burden on amateur radio operators. Structures that exceed this height typically pose a potential hazard to air traffic, particularly for low-flying aircraft approaching or departing from airports. By establishing 200 feet as the cut-off point, the FAA balances the interests of amateur radio operators with necessary safety protocols to protect aviation. Resources and regulations surrounding antenna structures may vary slightly based on local laws and specific locations; however, the 200-foot threshold is a widely accepted standard under FAA guidelines. This ensures compliance and minimizes risk for those engaging in amateur radio activities while maintaining airspace safety.
