Frequency range of the UHF?

• A. SWE results
• B. C-Schools
• C. Answer
• D. 2-5 GHz

Answer: (A)

UHF stands for Ultra High Frequency, a segment of the radio spectrum used mainly for line-of-sight communications and certain radar systems. The standard range for UHF is about 300 MHz up to 3 GHz. Frequencies higher than that enter the SHF band, while lower frequencies fall into VHF.

Among the given options, the only one that even resembles a frequency range is the numeric range, but 2–5 GHz extends beyond the typical UHF upper limit (3 GHz) and overlaps into SHF, so it isn’t a precise UHF band. The other two options are not frequency ranges at all, so they don’t describe the UHF spectrum.

The key takeaway to memorize is that UHF runs roughly 300 MHz to 3 GHz, and ranges like 2–5 GHz are not the accepted UHF band. If a test key marks a different option as correct, it may reflect a mismatch or formatting issue in the item rather than correct domain knowledge.
