The integral representations for the field components are evaluated numerically and compared with often used asymptotic formulas. It is found that the latter have a limited range of validity when the substratum is highly resistive. In general, the distance to the source cable must be allowed for in the interpretation of the observed fields. Numerical results for the relevant parameters are included. Author
