What are the factors affecting field strength?

The curvature of the Earth is also an important factor governing space wave propagation. The distance between the antennas determines the type of space wave propagation. The presence of obstacles in the path of the waves results in the loss of energy of the waves.

What is the field strength of surface of flat earth?

The field strength E_o of the wave at a unit distance from transmitting antenna depends on both on the power radiated by the transmitting antenna & directivity in vertical and horizontal planes. The overall field strength is calculated from this. The field strength of the surface wave of flat earth is given by E=AE_o/d.
