What frequency service operates in the UHF range?

• A. Very Low Frequencies
• B. Ultra High Frequencies
• C. Super High Frequencies
• D. Extremely High Frequencies

Answer: (B)

Ultra High Frequencies (UHF) is the correct answer because it specifically refers to frequencies that range from 300 MHz to 3 GHz. This range is vital for various forms of communication, including television broadcasting, mobile phones, and two-way radios. UHF signals are commonly used because they can support high data rates and have a relatively good wavelength for carrying signals over moderate distances, especially in urban environments.

In contrast, the other options refer to different frequency bands that are not within the UHF range. Very Low Frequencies operate below 30 MHz; Super High Frequencies fall between 3 GHz and 30 GHz; and Extremely High Frequencies range from 30 GHz to 300 GHz. These distinctions highlight the unique characteristics and applications associated with each frequency band.
