Which frequency range corresponds to UHF?

Which frequency range corresponds to UHF?

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

Answer: (C)

UHF means Ultra High Frequency, and this band runs from 300 MHz up to 3 GHz. That places it above VHF (30–300 MHz) and below the higher microwave region starting around 3 GHz. So the range 300 MHz to 3 GHz is the UHF band. This frequency range is commonly used for things like TV broadcasts, many mobile and wireless services, and Wi‑Fi; signals in this band tend to be more line-of-sight and require smaller antennas, compared with lower frequencies. The other ranges belong to different bands: 3–30 MHz is HF, 30–300 MHz is VHF, and 3–30 GHz is SHF/microwave, not UHF.
