 A transmitting antenna at the top of a tower has a height 32 m and that of the receiving antenna is 100 m. What is the maximum distance between them for satisfactory communication in LOS mode? Given radius of earth `6.4 xx10^(6)` m

Text Solution

Verified by Experts

`h_(T)=32m.h_(R)=100m`
R=`6.4xx10^(6)m`
`d_(M)=sqrt(2Rh_(T))+sqrt(2Rh_(R))` =`(64xx10^(2)xxsqrt(10))+(8xx10^(3)xxsqrt(10))=144xx10^(2)sqrt(10)m`
`d_(M)`=45.5km.
