    Name the type of waves which are used for line of sight (LOS) communication. What is the range of their frequencies? A transmitting antenna at the top of a tower has a height of 20m and the height of the receiving antenna is 45m. Calculate the maximum distance between them for satisfactory communication in LOS mode. (Radius of the Earth = 6.4 xx 10^(6) m)

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