UHF frequencies range from 300 MHz to 3 GHz. Which description best characterizes this band?

• A. It is within the VHF band
• B. It is used for long-distance transmissions
• C. It spans 30 kHz to 3 MHz
• D. It ranges from 300 MHz to 3 GHz

Answer: (D)

UHF is defined by its frequency range, typically from 300 MHz up to 3 GHz. This places it above the VHF band, which ends at 300 MHz, and just below the SHF band, which starts at 3 GHz. So the description that it ranges from 300 MHz to 3 GHz best characterizes UHF. The alternative that it sits within the VHF band isn’t accurate because VHF ends at 300 MHz. The notion of long-distance transmissions isn’t a defining trait of UHF, since UHF signals are largely line-of-sight and require repeaters or higher power for long-range links. The span from 30 kHz to 3 MHz is far too low for UHF, which sits in hundreds of MHz to a few GHz.
