The interference in the nighttime to MF radio broadcasting from foreign radio waves is a serious probrem. For that purpose, the construction of new relay stations and re-arrangement of frequency allocation are continued now. Recently, we have developed an unprecedented new type of MF receiving antenna device containing narrow directional characteristics applying the principle of the direction finder. This device will strongly contribute to reduce the above mentioned interference. The outline of the performance of this device and its characteristic features will be introduced here.
