The height of a transmitting antenna is ...

The height of a transmitting antenna is 68 m and the receiving antenna is at the top of a tower of height 34 m. Calculate the maximum distance between them for satisfactory transmission in line of sight mode. (radius of Earth = 6400 km)
`h_t = 68 m , h_r = 34 m, R= 6400 km = 6.4 xx 10^6 m`

Text Solution

Verified by Experts

`d_("max") = sqrt(2Rh_t) + sqrt(2Rh_r)`
`=(2xx 6.4 xx 10^6 xx 68) +sqrt(2 xx 6.4 xx 10^6 xx 34)`
`=sqrt(870) xx 10^3 + sqrt(435) xx 10^3`
`= 29.5 xx 10^3 + 20.9 xx 10^3`
`= 50.4 xx 10^3` m
`=50.4 km`
