Abstract
This study experimentally clarifies that the causes by which the radio control clock sometimes fails to receive the standard time signal in the indoors are in the following two factors: (1) the shielding by the conductive materials (used for column, pillar, floor and so on) existing close to the radio control clock. (2) The missing of tuning and the change of Q of the antenna due to the closely existing conductive materials.
