If the height of a TV transmitting antenna is 128 m, how much square area can be covered by the transmitted signal if the receiving antenna is at the ground level? R = 6400 km.

If a transmitting antenna of height 105 m is placed on a hill, then its coverage area is

The distance of coverage of a transmitting antenna is 12 . 8 km . Then the height of the antenna is (Given that redius of earth = 6400 km)

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)

A TV tower has a height of 200 M. How much population is covered by TV transmission if the average population density around the tower is 1000//km^2 ?

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
