To take into account the loss in the cable, we just have to deduce the 3 dB loss from the 18 dBi gain and use a modified antenna gain of G = 15 dBi. In one click we find the electrical field strength E = 1.4 V/m, the magnetic field strength H = 3.7 mA/m and the power density S = 5.0 mW/m2.
Types of Data: Primary and Secondary data. There are many ways of classifying data. A common classification is based upon who collected the data.
