The frequency 5 MHz lies in which RF band?

The frequency 5 MHz lies in which RF band?

• A. High Frequency
• B. Very High Frequency
• C. Ultra High Frequency
• D. Super High Frequency

Answer: (A)

RF bands are defined by approximate frequency ranges. High Frequency spans about 3 to 30 MHz. Very High Frequency starts at 30 MHz, Ultra High Frequency starts around 300 MHz, and Super High Frequency begins near 3 GHz. Since 5 MHz sits between 3 and 30 MHz, it belongs to the High Frequency band. This band is known for long-distance propagation via ionospheric reflection, which is why shortwave and some amateur or international communications use it. The other bands start at higher frequencies, so 5 MHz is well below their lower limits.
