Which term describes the frequency range that includes 400, 500, 700, and 900 MHz?

Which term describes the frequency range that includes 400, 500, 700, and 900 MHz?

• A. VHF - Very High Frequency
• B. band
• C. UHF - Ultra High Frequency
• D. GPS - Global Positioning

Answer: (C)

Ultra High Frequency is the range from about 300 MHz up to 3 GHz. The numbers 400, 500, 700, and 900 MHz all fall within that interval, so they’re described by the UHF band. VHF ends at 300 MHz, so it wouldn’t include these values. GPS refers to a specific navigation service that uses higher frequencies (around 1.5 GHz and 1.2 GHz), not the general name for this spread. The generic term “band” is too broad here; UHF precisely identifies the range containing those frequencies.
