I came across this info, might be of some value.
Ref: The Satellite Experimenters Handbook, Pg 9-6
Max Dist (range) = 2R * arcos [R/(R+h)]
Where R = 6,371 km and
h = 1,459 km at Apogee (AO-7)
h = 1,440 km at Perigee (AO-7)
Therefore the maximum possible communication distance via AO-7 at Apogee =
Therefore the maximum possible communication distance via AO-7 at Perigee =
The difference in range from apogee to perigee appears to be only 33 km.
