Which frequency range corresponds to UHF communication?

  1. 30 to 300 MHz

  2. 300 to 3,000 MHz

  3. 1 to 30 MHz

  4. 3,000 to 10,000 MHz

The correct answer is: 300 to 3,000 MHz

The frequency range that corresponds to UHF (Ultra High Frequency) communication is 300 to 3,000 MHz. This band is commonly used for communication technologies such as television broadcasting, mobile phones, and two-way radios. By operating within this frequency range, UHF communication can effectively penetrate buildings and obstructions, making it suitable for urban environments and improving signal clarity over distances. Understanding the classification of radio frequencies is essential in communication, as different bands serve specific purposes and have varying propagation characteristics. The UHF range allows for smaller antennas and has less interference from physical barriers compared to lower frequency bands, which is especially useful in emergency and public safety communications.
