CAAT 2 Infantry Knowledge Practice Test

VHF spans roughly 30 to 300 MHz, and Very High Frequency High sits in the middle portion of that band. The 90–225 MHz range is chosen for VHFH because it lies well above the lowest part of VHF (which is closer to 30–90 MHz) and below the upper edge where many systems start being categorized into higher bands. This mid-range is a common designation for VHF High in this context. The other options lie outside that specific sub-band: 2–29.9999 MHz is HF, 30–90 MHz is the lower part of VHF, and 225–2 GHz includes frequencies that are typically considered higher bands, not VHF High.
