A transmitting antenna at the top of a tower has a height 32m and that of the receiving antenna is 50m. What is the maximum distance between then for satisfactory communication in line of sight made ? `R = 6.4 xx 10^6`m

A transmitting antenna at the top of a tower has a height of 50 m and the height of the receiving antenna is 32 m. What is the maximum distance between them for satisfactory communication in line of sight mode ? (Radius of the earth (R ) = 6.4xx10^6 m) ( sqrt10 =3.16)

Name the type of waves which are used for line of sight (LOS) communication. What is the range of their frequencies? A transmitting antenna at the top of a tower has a height of 20m and the height of the receiving antenna is 45m. Calculate the maximum distance between them for satisfactory communication in LOS mode. (Radius of the Earth = 6.4 xx 10^(6) m)

The height of a transmitting antenna is 68 m and the receiving antenna is at the top of a tower of height 34m. Calculate the maximum distance between them for satisfactory transmission in line of sight mode, R = 6400 km

A transmitting antenna of height h and the receiving antenna of height 45 m are separated by a distance of 40 km of satisfactory communication in line of sight mode. Then the value of h is (given radius of earth is 6400 km)

The height of a T.V. tower is 300 m. What is the maximum distance upto which T. V. signals can be received ? ( R = 6400 km)
