The height of a transmitting antenna at the top of a tower is 25 m and that of receiving antenna is, 49 m. The maximum distance between them, for satisfactory communication in LOS (Line-Of-Sight) is m. The value of K is . (Assume radius of Earth is m) [Calculate upto nearest integer value]

Answer: 192

Solution

The maximum LOS distance is Double subscripts: use braces to clarifyd = \sqrt{2h_{tR}_{e}} + \sqrt{2h_{rR}_{e}} = \sqrt{2 \times 25 \times 64 \times 10^{5}} + \sqrt{2 \times 49 \times 64 \times 10^{5}} where $Missing argument for \sqrt\sqrt{2 ×
