ATTENUATION OF RADIO WAVES 



Table 7.5. Values of m and b in the regression line y = mx + b, 

 where y is the logarithm of the total path attenuation, y, b is the value of y when the absolute humidity 

 is 1 g/m^ and x is the logarithm of the absolute humidity.

 logarithyn of the total path absorption, x is the logarithm of the absolute humidity, b is 

 the value ofy when the absolute humidity is 1 g/m^.
