The distribution of the noise level is subject to the normal or logarithmic normal distribution. Due to the absence of stable maxima in the organization of radio communication in the 100 to 400 MHz range it is favorable to tune out noise by frequency. The quality of communication may be increased either by increase of the distance between the antenna and the distribution unit with change of the direction or by increasing the power of the signal. The noise voltage of 3 to 5 mkV at 390 MHz obtained as a result of the measurements is comparable to the sensitiviy of the receivers of DM400 radio relay stations, which operate in this frequency range. This should be taken into consideration by planners in the placement of equipment on the substation site. The antenna should be located at the maximum possible distance from the distribution unit.
