Question 7A3

Very High Frequency (VHF) is officially defined as the band of radio frequencies from 30 MHz to 300 MHz. This range is characterized by wavelengths between 1 and 10 meters. VHF signals primarily travel by line-of-sight propagation, making them ideal for local communication, FM radio broadcasting, television broadcasting, aircraft navigation, and amateur radio operations on bands like 6 meters (50-54 MHz), 2 meters (144-148 MHz), and 1.25 meters (222-225 MHz). Option B, 3-30 MHz, describes the High Frequency (HF) band, commonly known for its ability to support long-distance skywave propagation. Option C, 300-3,000 kHz (or 0.3-3 MHz), falls within the Medium Frequency (MF) band, used for AM radio broadcasting and some maritime communications. Option D, 10-30 MHz, is a subset of the HF band and not the full VHF range.
