A transmitting antenna of height 25 m is fitted at the top of a tower of height 20m. What is the height of the receiving antenna from ground level if the maximum distance between transmitting antenna and receiving antenna on ground is 56 km. Radius of earth = 6400 km.

What does the term LOS communication mean ? Name the types of waves that are used for this communication. Which of the two heights of transmitting antenna and height of receiving antenna can affect the range over which this mode of communication remains effective?
