- - -Soil effect: the reduction of the soil effect for small distance/height values.


Soil effect according to general method (7.3.1) 5 m beam height

- - -Abar barrier effect: changes to the dimming of the Dz barrier and correction of Kmet weather effects to eliminate deficiencies with low and long distances between source and receiver.



- - -Cmet weather correction: formalism unchanged, but significantly enlarged in relation to high-altitude sources.
