Errors in direction finding due to nonvertical channel sections over finitely conducting ground have been investigated. The results show that if the direction of the lightning flash is estimated from the initial peak of the magnetic radiation field then, for the conductivity of the ground in the range of 0.01 mho/m to 0.001 mho/m, the propergation errors caused by the inclination of the channel at distances of about 10 km or more would be less than about 1°.
