What frequency range is classified as Ultra High Frequency (UHF)?

What frequency range is classified as Ultra High Frequency (UHF)?

• A. 3 to 30 MHz
• B. 30 to 300 MHz
• C. 300 to 3000 MHz
• D. 3000 to 30,000 MHz

Answer: (C)

Ultra High Frequency sits in the range between 300 MHz and 3,000 MHz (3 GHz). This puts it above VHF and below SHF, with wavelengths roughly from 1 meter down to about 10 centimeters. This region is characterized by line-of-sight propagation and compact antennas, making it ideal for things like TV, cellular networks, and Wi‑Fi. Among the options, the range from 300 to 3,000 MHz matches UHF exactly. The other ranges correspond to different parts of the spectrum: 3 to 30 MHz is HF, 30 to 300 MHz is VHF, and 3,000 to 30,000 MHz is the SHF region.
