A transmitting antenna at the top of a tower has a height 32 m and the height of the receiving antenna is 50 m . What is the maximum distance between them for satisfactory communication in LOS mode ? Given radius of earth `6.4 xx 10^(6) `m .

Text Solution

Verified by Experts

`d_(m)=sqrt(2xx64xx10^(5)xx32)+sqrt(2xx64xx10^(5)xx50m)`
`=64xx10^(2)xxsqrt(10)+8xx10^(3)xxsqrt(10)m`
`=144xx10^(2)xxsqrt(10)m = 45.5"km"`
