What is the LORAN frequency range?

• A. 3 kHz - 30 kHz
• B. 3 MHz - 30 MHz
• C. 10 kHz - 14 kHz
• D. 90 kHz - 110 kHz

Answer: (D)

LORAN signals are transmitted in the low-frequency band around 100 kHz, specifically about 90 to 110 kHz. This frequency range enables long-range ground-wave propagation, so receivers can pick up signals from transmitters hundreds or thousands of miles away, which is essential for a navigation system that relies on precise timing from multiple stations. The other frequency options fall outside this band and don’t offer the same dependable long-range coverage in practice. Therefore, the LORAN frequency range is approximately 90–110 kHz.
