What is the frequency spectrum for UHF?

• A. 300-3000 MHz
• B. 3-30 GHz
• C. 2182 kHz
• D. 30-300 MHz

Answer: (A)

Ultra High Frequency spans from 300 MHz up to 3 GHz (which is 3000 MHz). That boundary makes 300-3000 MHz the correct range for UHF, since it sits above VHF (30-300 MHz) and below SHF (3-30 GHz). The other options don’t fit because one is in the VHF band, another is in the SHF band, and the remaining single frequency sits in the MF region rather than UHF.
