The device has an electric conductor (26) comprising a longitudinal section (L1) of line-shaft resistance (Z0) for electromagnetic waves between a proximal end and an electrode pole (22). The conductor has another short longitudinal section (L2) with line-shaft resistance (Z1) and inner dimension (d-iel) of 0.25 in comparison with the former longitudinal section, where conductor is directly provided at the former longitudinal section in a limited manner. The latter resistance is larger or smaller than the former resistance, and is larger or smaller than load resistance. |
