Case study 7
Calculate the 0.5% and 0.1% worst month rainfall attenuation for 12.75 GHz at Canberra (1% W.M. rain fall is 3mm/hr and 0.1% W.M. rain fall is 12 mm/hr).
Solution 7
Using Flavin's relation for 1% WM A(dB) = (0.0308 * 12.5 - 0.1872) 3 = 0.59 dB
Recalculating for 0.1% W.M.
A(dB) = (0.0308 * 12.5 - 0.1872) 12 = 2.37 dB
