The height of a transmission antenna is \(49 \mathrm{~m}\) and that of the receiving antenna is \(64 \mathrm{~m}\). What should be the maximum distance between them for line of sight transmission?
- A \(50.1 \mathrm{~km}\)
- B \(53.6 \mathrm{~km}\)
- C \(43.6 \mathrm{~km}\)
- D \(65.2 \mathrm{~km}\)
Answer & Solution
Correct Answer
(B) \(53.6 \mathrm{~km}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} d_{\max } & =\sqrt{2 r h_T}+\sqrt{2 r h_r} \\ h_T & =49 \mathrm{~m}, h_p=64 \mathrm{~m}, \\ r & =6400 \mathrm{~km} \end{aligned}\) So, maximum distance (in \(\mathrm{km}\) ) is…
