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.
