PURPOSE:To eliminate the hooking of an antenna on an obstacle, to prevent the free activity of an animal from being blocked, and to reduce rejection symptoms given by a transmitter in the activity and the ecological research, etc., of the animal by the transmitter, by providing a cover made of artificial leather or a resin film, etc., on the base part of the antenna. CONSTITUTION:In the antenna of the transmitter loaded on a mobile body, the antenna (1) is mounted on a transmitter main body (3), and the base part (2) of the antenna is formed by providing the cover made of the artificial leather (4) or the resin film (5), etc. In such constitution, the cover made of the artificial leather (4) or the resin film (5), etc., on the base part can prevent a coil-shaped spring from being brought into contact with the outside, and can smooth the motion of the antenna. In such a way, the hooking of the antenna on the obstacle can be eliminated, and no free activity of the animal, etc., can be blocked, and the rejection symptoms given by the transmitter can be reduced in the activity and the ecological research of the animal by the transmitter.
