Low VHF Broadcast Television

• The lower end of the VHF range is used to broadcast television shows in many countries. In the United States, the low VHF stations are channels 2 through 6. These channels correspond to frequencies ranging from 59 to 88 MHz.
  
  

High VHF Broadcast Television

• The higher end of the VHF range is also used for television broadcasting. In the United States, the high VHF stations are channels 7 through 13 and correspond to the frequencies from 175 to 216 MHz.
  
  

Antenna Size

• The frequency of a radio wave is inversely proportional to the wavelength of one complete cycle. The lower the frequency, the longer the wavelength. Antennas must have a length of one quarter the wavelength of the radio wave. Low-VHF antennas must therefore be longer than high-VHF antennas.
  
  

Transmitter Power

• The low end of the VHF radio frequency range requires less power to transmit television an equivalent distance than the high end of the VHF range because the voltage required to generate a VHF signal has a positive correlation to frequency. The higher the frequency, the higher the voltage needed to generate the same transmission capability.
