The subject innovation is to when related to a bus equipped with a motorized satellite receiving antenna, generally stationary antenna is not only bad reception sensitivity, the driving where the vehicle receives the interference disturbing the radio wave received from the fixed antenna the noise on TV and the audio is causing the problem was not properly convey the information to the passengers. Thus sikimyeo the subject innovation, the installation of the motor in the loop trim on the bus, and out the hole in the roof trim for the bus projecting a rotating shaft of the motor, to install the support plate is formed to one side in the motor rotation shaft to the hollow support portion, and the motor and forming the wheel to the left and right lower portion of the supporting plate to rotate with the rotation, the binary install the supports in the upper middle portion of the support plate, and inclined to support the respective one side and the other side support portion of the support plate and the top of the carrier state parabola the antenna, and to install a reception tuner to the reception line of the parabolic antenna, and thereby install a direction control switch to a power supply line of the motor, as it improves the reception sensitivity such as television and audio accurate than the occupant to may provide improved information and services are those features.
