Q30.If the sum of the heights of transmitting and receiving antennas in the line of sight of communication is fixed at 160 m, then the maximum range of LOS communication is _______ km (Take radius of Earth = 6400 km)
What This Question Tests
The problem tests the formula for the maximum line-of-sight communication range, requiring calculation of individual antenna ranges and summing them, given the sum of antenna heights.
Concepts Tested
Formulas Used
d_T = √(2Rh_T)
d_R = √(2Rh_R)
d_max = d_T + d_R
