The frequency spectrum for VHF is which range?

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

Answer: (A)

VHF is the band that sits between HF and UHF, defined as roughly 30 to 300 MHz. This range corresponds to wavelengths of about 10 meters down to 1 meter. Signals in this band travel mainly by line of sight and are less affected by ionospheric reflection than lower frequencies, which is why VHF is favored for things like FM radio, many television channels, and aviation and marine communications. The other options align with different bands: 3–30 MHz is the HF band, 300–3000 kHz is MF, and 30–3000 kHz spans LF/MF, not VHF. So the correct range for VHF is 30–300 MHz.
