A TV transmission tower antenna is at a height of 20m. Suppose that the receiveing antenna is at.
(i) ground level
(ii) a height of 5m
The increase in antenna range in case (ii) relative to case (i) is n%.
The value of n, to the nearest integer, is..........

A TV transmission tower of antenna is at a height of 20 m. How much service area can it cover if the receiving antenna is (i) at ground level (ii) at a height of 25 m ? Calculate the percentage increase in area covered in case (ii) relative to case (i).

A T V transmission tower antenna is at a height of 20 m. How much service area can it cover if the receiving antenna is (i) at ground level, (ii) at a height of 25 m? Calculate the percentage increase in area covered in case (ii) relative to case (i).

A TV transmission tower antenna is at a height of 20m. The percentage increase in area covered in case if the receiving antenna is at ground level to that at a height of 25 m is (Radius of earth =6.4xx10^(6)m )

A TV transmitting antenna is 81 m tall. How much service area it can cover if the receiving antenna is at the ground level? (Radius of earth= 6.4xx10^(6)m )

A TV transmitting antenna is 125 m tall. How much service area this transmitting antenna cover, if the receiving antenna is at the ground level? Radius of earth = 6400 km .

If we take 2 cases as: 1. antenna is at height 20m 2. antenna is at 25m above ground level then the difference in range between two cases in percentage in n%. Find n

A TV transmitting antenna is 128m tall.If the receiving antenna is at the ground level the maximum distance between them for satisfactory communication in line of sight mode is (radius of the earth 6.4times10^(6)m )

A TV transmission tower has a height of 140 m and the height of the receiving antenna is 80 m. What is the maximum distance upto which signals can be broadcasted from this tower in LOS (Line of Sight) mode? (Given: Radius of earth = 6.4 xx 10^6 m )

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

A transmitting antenna of height 25 m is fitted at the top of a tower of height 20m. What is the height of the receiving antenna from ground level if the maximum distance between transmitting antenna and receiving antenna on ground is 56 km. Radius of earth = 6400 km.
