What frequency range is referred to as UHF?

• A. 3 to 30 MHz
• B. 30 to 300 MHz
• C. 300 to 3000 MHz
• D. 30 to 3000 MHz

Answer: (C)

The frequency range referred to as UHF (Ultra High Frequency) is from 300 to 3000 MHz. This range is significant for various applications including television broadcasting, mobile phones, and other forms of wireless communication. UHF frequencies are advantageous due to their ability to penetrate obstacles like buildings better than lower frequencies and their relatively smaller wavelength, which allows for more compact antennas. Understanding this range is crucial for operators as it helps in selecting the appropriate frequencies for communication and ensuring compliance with regulations governing amateur radio use.
