Suppose thatthere are two antennas a and b respectively. a is transmitter withheight 50 meters while b is receiver with height 15 meters. considering los (line-of-sight),
a) compute thathow much distance it should cover by transmission?
b) if distance is30 km then what height is required for antenna b while consideringsame height of antenna a as mentioned in abovestatement?

   (a) 45 km

                  (b) 53 km

Explanation:

(a)        

       h = Height of antenna.

        D =Distance between antenna's horizon in km  

        k =adjustment factor and it is 4/3 commonly.

       Formula:  

                             =3.57 x 12.64

                             = 45 km

(b)

      Distance D=30km

                 h = (30 /4.122)²  

                 h = (7.28)2 = 52.96 ˜ 53m.
