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 `6.4xx10^(6)m`. |

Answer» `d_(m)=sqrt(2xx64xx10^(5)xx32)+sqrt(2xx64xx10^(5)xx50)m` `=64xx10^(2)xxsqrt(10)+8xx10^(3)xxsqrt(10)m` `=144xx10^(2)xxsqrt(10)m=45.5km` |
