The skip distance is dependent upon a variety of factors.

Skip distance formula in ut. For a flat earth skip distance is given as. Skip distance skip zone in figure 2 19 note the relationship between the sky wave skip distance the skip zone and the ground wave coverage. The skip distance is the distance from the transmitter to the point where the sky wave is first returned to earth.

Sandeep anand i am a mechanical engineer with more than ten years of work experience in the field of welding and ndt. Is first returned to earth. Typically as the frequency increases a lower angle of radiation is needed to return the signals to earth in a shorter distance.
