What is the UHF frequency range?

Explanation:
The UHF frequency range used in aviation is defined as 225.000 to 399.975 MHz. This upper boundary is set at 399.975 MHz to keep a precise, standardized limit just below 400 MHz. In practice, UHF voice communications are carried using frequency modulation (FM) for reliability in noisy environments, though some references may mention various modulation possibilities. So the range 225.000 to 399.975 MHz best matches the standard UHF band.
