Which frequency range corresponds to VHF?

Which frequency range corresponds to VHF?

• A. 3-30 MHz
• B. 30-300 MHz
• C. 300 MHz-3 GHz
• D. 1-10 GHz

Answer: (B)

VHF covers the frequency range of 30 to 300 megahertz. This band sits above HF (3–30 MHz) and below UHF (300 MHz–3 GHz), with wavelengths roughly from 10 meters down to 1 meter. Because of these wavelengths, VHF signals propagate mainly by line of sight, making them ideal for applications like FM radio, television, and aviation communications. The other options map to different bands: 3–30 MHz is HF, 300 MHz–3 GHz is UHF, and 1–10 GHz is largely UHF/SHF. So, the 30–300 MHz range is the VHF band.
