This paper aims at the ineffective cases of HF radio interference within the operational distance from the sky-wave interference equipment, to put forward a conclusion that the Sporadic E-layer in the ionosphere can stop waves from arriving at the target radio by means of analysis of sky-wave propagation principles and the influencing factors between interference effects. Meanwhile, this paper puts forward ways to interfere the antenna due to different options of different distances and different heights of ionospheres, when the sky-wave interferes of the antenna radiation direction thus resolves the bad interference results caused by Sporadic E layer and testifies the conclusions through experiments as well through the study.
