What frequency range is referred to as VHF?

A30 kHz to 300 kHz
B30 MHz to 300 MHz
C300 kHz to 3000 kHz
D300 MHz to 3000 MHz

Why The ITU divides the radio spectrum into decade-wide bands, each running from 3 to 30 to 300 and so on. VHF (Very High Frequency) is the 30 MHz to 300 MHz decade, which is where the 6 meter, 2 meter and 1.25 meter ham bands live. Below it is HF at 3 MHz to 30 MHz, and above it is UHF at 300 MHz to 3000 MHz.

Watch out The 300 MHz to 3000 MHz choice is UHF, home of the 70 cm band, and the kilohertz ranges are the LF and MF bands far below any VHF allocation.

Each band is a decade: HF 3-30 MHz, VHF 30-300 MHz, UHF 300-3000 MHz. Just slide the decimal point.
