Which option correctly pairs the UHF spectrum with its range?

• A. 300-3000 MHz
• B. 3-30 GHz
• C. 2182 kHz
• D. MF

Answer: (A)

UHF is the portion of the radio spectrum from 300 MHz up to 3000 MHz. This range sits above VHF (30–300 MHz) and below SHF (3–30 GHz), so the pairing 300–3000 MHz matches the UHF band exactly. The shorter wavelengths in this band—about 1 meter down to 0.1 meter—make UHF signals well-suited to line-of-sight communications and compact antennas, which is why you see them used for mobile networks, Wi‑Fi, and certain television and radar applications. The other options don’t fit UHF: 3–30 GHz is the SHF range, 2182 kHz is in the MF band, and MF refers to a broader range that does not describe UHF.
