This is the experimental research of testing out the reception interfered area and of its improvement at the suburbs of Dac gu. As a result of its research, it was found out that the moust important causes of reception interference were the weak field intensity and at the same time the strong ghost interference. we have drawn, 10 element high gain antenna according to its result. we have tried its equipping method and checked the most improving methods. It was possible to improve D/U above 4.7dB at the maximum using the high gain antenna and there was some cases of (improving D/U) its improvement above 2.lidB moving the antenna 20m.
