Both this method and the traditional singlechannel
method require an FM band antenna.
Two common antennas used for FM radio
receivers are the half wave and quarter wave
antennas. These are typically metallic conductors
with a linear length equal to ½ or ¼ the
wavelength of the desired frequency. In order to
receive the FM radio band (87.8MHz to
108.0MHz) an antenna tuned to a middle
frequency of 97.9MHz is used. To find the
wavelength of this frequency we use Equation 1,
