The Emergency Beacon Broadcast operates in which frequency range?

The Emergency Beacon Broadcast operates in which frequency range?

• A. 90 to 511.9999 MHz
• B. 100 to 300 MHz
• C. 60 to 120 MHz
• D. 500 to 700 MHz

Answer: (A)

The Emergency Beacon Broadcast is designed to be heard by as many receivers as possible, so it uses a broad mix of VHF/UHF frequencies. The 90 to 511.9999 MHz range spans essential VHF and lower UHF bands, giving compatibility with a wide variety of radios, aircraft transceivers, and ground units that might be monitoring different frequencies during an emergency. This wide coverage increases the chance the beacon is detected quickly, regardless of which specific channel is in use by nearby assets. Narrower ranges would miss portions of the spectrum that emergency responders and search-and-rescue assets rely on, making detection less reliable. So the 90 to 511.9999 MHz range is the appropriate choice to ensure broad reception.
