A transmitting antenna at top of a tower has a height of 50m and the height of receiving antenna is 80m. What is the range of communication for Line of Sight (LoS) mode? [use radius of earth = 6400km]

Correct Option - 2


Detailed Solution:

Range of communication

= d₁ + d₂

= $\sqrt[]{2R{h}_T}+\sqrt[]{2R{h}_R}$  

= $\sqrt[]{2\times 6400}\left(\sqrt[]{0.05}+\sqrt[]{0.08}\right)$  

= 57.28 km
