Remarks

・E/E0=1+R*e^(-j*δ).
・|E/E0|≈(1+R^2+2*R*cos(δ))^0.5
・δ=2*π/λ*(r2-r1).
・Earth is assumed to be perfect conductor and Ground Wave Propagation is disregarded in this calculation.
・Both Ionospheric Reflected Wave and Tropospheric Reflected Wave are disregarded in this calculation.
・It is assumed that the reflection is the horizontal.
・|E/E0| becomes equal with zero if h2 equals Height Pattern Pitch accurately.
・R:Reflection Coefficient.Calculation of Reflection Coefficient.
