Q. The maximum line-of-sight distance $d_{M}$ between two antennas having heights $h_{T}$ and $h_{R}$ above the earth is
A) $\sqrt{R(h_{T} + h_{R})}$
B) $\sqrt{2R(h_{T} + h_{R})}$
C) $\sqrt{Rh_{T}} + \sqrt{2Rh_{R}}$
D) $\sqrt{2Rh_{T}} + \sqrt{2Rh_{R}}$
Explanation
The correct answer is Option D: $\sqrt{2Rh_{T}} + \sqrt{2Rh_{R}}$.
