4.4.4    Reference: Estimation methods of RX/TX signal loss by physical obstructions 

Attenuation with the obstacle calculates easily in the following method. 

I.  Estimation procedure with the chart (for cylindrical obstacles) 

i)  Estimate the distance (R) from the obstacle;      R (m) 
ii)  Estimate the effective diameter (d) of the obstacle; d (m)   
iii)  Read off the loss (L

B

) in the Chart I;                        L

B

 (dB) 

iv)  Determine whether the loss (L

B

) is allowable.

d=0.2m 

Pole 
or 
Mast 

R=5m 

Example 
i)  R:5 
ii)  d:02m 
iii)  L
