What frequency range does Ultra High Frequency (UHF) operate within?

• A. 30 to 300 MHz
• B. 470 to 806 MHz
• C. 300 to 470 MHz
• D. 806 to 1000 MHz

Answer: (B)

Ultra High Frequency (UHF) operates within the frequency range of 300 MHz to 3 GHz. However, in the context of the options provided, the correct answer is 470 to 806 MHz, as it falls within the defined UHF spectrum and is commonly used for television broadcasting, cellular phones, satellite communications, and various forms of two-way radio communication. The specific range of 470 to 806 MHz is significant because it is frequently utilized for television channels and is important for public safety communications, making it essential for understanding UHF's practical applications. The other ranges listed do not accurately capture the UHF band as recognized by regulatory bodies, which clarifies why the answer provided is the most accurate choice regarding the UHF frequency range.
