Which frequency range includes the 400 MHz, 500 MHz, 700 MHz and 900 MHz frequencies?

Which frequency range includes the 400 MHz, 500 MHz, 700 MHz and 900 MHz frequencies?

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

Answer: (C)

Frequencies like 400, 500, 700, and 900 MHz sit in the Ultra High Frequency range. This band spans roughly 300 MHz up to 3 GHz, so all of these values fall inside it. The VHF range only goes up to 300 MHz, so it’s too low for these frequencies. The term band is a generic label and not a specific range, so it doesn’t name the correct category. GPS refers to a system that uses specific frequencies (around 1.2 and 1.5 GHz), which happen to lie in UHF, but the question asks for the named frequency range, not a system. Therefore, Ultra High Frequency is the correct range.
