A transmitting antenna has a height of 320 m and that of receiving antenna is 2000 m . The maximum distance between them for satisfactory communication in line of sight mode is d . The value of d is ________ km .

Step-by-step solution

Recall the formula of maximum distance between transmitting antenna and receiving antenna for satisfactory communication in terms of the radius of the earth and height of antennas, d = 2 R h 1 + 2 R h 2 ⇒ d = 2 × 6400 × 0 . 32 + 2 × 6400 × 2 ≈ 224   km
