What is the UHF frequency range?

• A. 300-3000 MHz
• B. 30-300 MHz
• C. 3-30 GHz
• D. 300-3000 kHz

Answer: (A)

Ultra High Frequency comprises the part of the radio spectrum from 300 MHz up to 3 GHz. That means the range 300-3000 MHz matches UHF exactly, since 3 GHz equals 3000 MHz. This places UHF above VHF (30-300 MHz) and below SHF (3-30 GHz). The other options correspond to different bands: 30-300 MHz is VHF; 3-30 GHz is SHF; 300-3000 kHz is about 0.3-3 MHz, which is in the MF/low-frequency region, not UHF.
