Is there a standard equation for calculating the reflection angle on an
OATS/SAC with a varying height antenna? Or can someone give me some
pointers to help me figure it out myself
Make a drawing. The only odd bit is that cotangents occur.
Height of Tx = T, height of Rx = R. Distance between antennas = S
Angle between incident ray and plane = angle between reflected ray and
plane = alpha.
T*COT[alpha] + R*COT[alpha] = S
COT[alpha] = S/(T+R)
Angle of reflection = 180-2[alpha]
I hope!
