What is the frequency range for UHF?

The frequency range for UHF (Ultra High Frequency) is defined as between 300 MHz and 3 GHz (3000 MHz), but in the context of specific applications, it is commonly referenced from 225 MHz to 511.999 MHz, particularly in military communications. This range is significant for various uses, including satellite communications, television broadcasting, and mobile services.

The selection of the range from 225 to 511.999 MHz highlights its critical role in military communications, where specific bands within UHF are assigned for various operational purposes, such as tactical communications and air-to-ground links. By understanding this frequency range, you can better grasp the operational capabilities and limitations of UHF communication systems commonly utilized in military applications.

Other frequency ranges listed in the choices do not align with the UHF category, which makes the correct option distinct as it focuses on the specific military application rather than the broader microwave or high-frequency radio ranges defined elsewhere.
