Which radio frequency band operates from 450MHz to 460 MHz?

The radio frequency band that operates from 450 MHz to 460 MHz falls within the Ultra High Frequency (UHF) range. UHF is characterized by wavelengths from approximately 300 MHz to 3 GHz, making it suitable for a variety of communication applications, including television broadcasting, mobile phones, and, importantly for firefighters, two-way radio communications.

In the context of firefighting and emergency services, understanding and utilizing the UHF band is crucial because it provides better penetration in urban environments, allows for more compact antenna designs, and supports a wider range of communication technologies. This frequency band is particularly effective for operations where short-range and reliable communication is necessary, such as coordinating on-site emergency responses.

The other frequency bands listed are defined based on different ranges of frequencies and have distinct characteristics and uses. Very High Frequency (VHF) operates between 30 MHz and 300 MHz; Low Frequency (LF) operates below 300 kHz; and Super High Frequency (SHF) operates from 3 GHz to 30 GHz. Understanding these distinctions helps clarify why the UHF band is the correct answer for this question.
