A TV transmission tower has height of 140m and the height of recieving antenna is 40m. What is the maximum disatnce upto which signals can be broadcasted from this tower in LOS(line of sight) mode?
(Given : radius of earth = 6.4 X 106 m)
65 km
48 km
80 km
40 km
Range of transmitting antenna -
- wherein
height of antenna
Radius of earth
let = maximum distance upto which signal can be braodcasted.
so,
Where ,R = Radius of earth
= Height of transmitter
= Height of Receiver
So,
65 km
Option 2)48 km
Option 3)80 km
Option 4)40 km
