Figure 8. SAR values in the vertical cross section in the middle of the human model for the exposure on the steel lattice mast with 4 dipoles (left) and close to the steel pole with 2 dipoles (right). The scale is normalized to 10 W kg<sup>−1</sup>. The squares (indicated by arrows) mark the location of the highest values of the SAR in the wrist.

Figure 7. Comparison of the values of the electric field at the line at the height of 1.5 m above the standing point in the direction from the FM antennas to the human model for the configuration with two dipole antennas. The values are presented with different lines: in one case (no man), it is calculated without the presence of the human body and in three cases with the human body located on at different distances from the FM antennas. The position of the human body is marked with arrows.
