Which frequency range corresponds to the designation UHF?

The designation UHF, which stands for Ultra High Frequency, corresponds to the frequency range of 300-3000 MHz. This band is widely used for various forms of communication, including television broadcasting, mobile phones, and two-way radios.

Understanding UHF is essential as it plays a critical role in modern telecommunications and broadcasting, where signals need to cover relatively long distances while maintaining clarity and quality. Frequencies in the UHF range are suitable for line-of-sight communication and can penetrate through obstacles better than higher frequencies, making them versatile in various applications.

The other choices represent different frequency bands: the first option refers to very low frequencies (VLF), the second to low frequencies (LF), and the fourth option corresponds to low frequency (VLF) again. None of these align with the UHF designation, which specifically requires the 300-3000 MHz range to be accurate.
