UHF refers to frequencies in what range?

Explanation:
UHF is the Ultra High Frequency band, which runs from 300 MHz up to 3,000 MHz (3 GHz). This places it above the VHF range (30–300 MHz) and below the SHF range (3–30 GHz). So the correct range describes signals from 0.3 to 3 GHz. The other options correspond to much lower frequencies (3–30 kHz), or much higher bands (30–300 GHz and beyond), which are not UHF. This band is commonly used for line-of-sight communications and applications requiring compact antennas due to its shorter wavelengths.
