What frequency range does UHF (ultra high frequency) cover?

• A. 300 to 3,000 MHz
• B. 30 to 300 MHz
• C. 3 to 30 MHz
• D. 30 to 1,500 MHz

Answer: (A)

The UHF (ultra high frequency) range is defined as covering frequencies from 300 MHz to 3,000 MHz. This frequency range plays a critical role in various forms of communication, including television broadcasts, mobile phones, and two-way radios, among others. The characteristics of UHF signals typically allow for transmission with a relatively small antenna, improved propagation through urban environments, and good penetration through structures, making them highly effective for modern communication systems. Understanding this frequency range is essential for EMTs as they use communication devices operating within the UHF spectrum to coordinate with other responders and dispatchers efficiently.
