Question

A transmitting antenna at the top of a tower has a height 32 m and that of the receiving antenna is 50 m. What is the maximum distance between them for satisfactory communication in line of sight mode? Given radius of Earth is 6.4 × 10⁶ m.

Answer 1

Given : h_t = 32 m, h_r = 50 m, R = 6.4 × 10⁶ m

To find : Maximum distance or range (d)

Formula : d = \(\sqrt{2Rh}\)

Calculation : From formula,
