Seachas sin, ní mheastar aon laghdú torainn le díraonadh don chonair sin, ríomhtar plána talún meánach coiteann don chonair S -> R, agus ríomhtar Aground gan aon díraonadh (Adif = 0 dB).
Otherwise, no attenuation by diffraction is considered for this path, a common mean ground plane for the path S -> R is calculated, and Aground is calculated with no diffraction (Adif = 0 dB).

Ach sa chás sin ní bhíonn na paraiméadair le haghaidh treo cliathánach agus laghdú torainn chomh soiléir sin.
But in this case the parameters for lateral directivity and attenuation are less obvious.
