The paper presents a brief overview of the main results of observations of the radio emission in polar coronal holes on the Sun obtained in a wide range of wavelengths with various radio telescopes. We analyze the results of observations of the polar coronal hole with RATAN–600 in a wide centimeter wavelength range of (1.03–30.7) cm. The obtained physical characteristics of the coronal hole above the north pole of the Sun are compared with the characteristics of the coronal holes located at lower latitudes.
