What does the UHF frequency range include?

The UHF (Ultra High Frequency) frequency range typically includes frequencies from 300 MHz to 3 GHz, but in the context of this question, it's important to recognize that specific sub-bands within the UHF range are often associated with certain applications or systems.

The option that correctly falls within the UHF spectrum is 450-512 MHz. This range is widely used for various types of communications, including two-way radio systems, public safety communications, and commercial applications. The frequencies in this range allow for effective line-of-sight communication, which is ideal for emergency services and other critical communication needs, as they can penetrate urban environments and maintain connectivity over varying distances.

The other frequency ranges listed do not fall under the UHF designation:

• The range 30-50 MHz is classified as the Low Frequency (LF) or very high frequency (VHF) spectrum, depending on specific allocations.
• The range 150-174 MHz also identifies as VHF, commonly used for various radio communications and public safety.
• The range 769-806 MHz is generally categorized in the upper UHF and is used for specific digital and analog communications but is less commonly encountered in standard UHF classifications.

Thus, the specified 450-512 MHz
