what is VHF radio? VHF operates at

what is VHF radio? VHF operates at a higher frequency range than HF, usually between 30-300 MHz. These transmissions, due to their higher frequency, penetrate through the Ionosphere, with little or no refraction. VHF propagation is 'line of sight' in nature and so is restricted to shorter-range communications

This is VHF radiation bed VHF operates in a high frequency range, 30-300 MHz between high frequency and normal. This is transmitted to high frequency and penetrates the ion sphere, small or non refracted. VHF propagation is a natural line of sight and also a limitation to short-range communication.
