SOLUTION: A metallic rod 2 being a device main body whose length is 1/2 wavelength of a reception frequency or below is provided. The metallic rod 2 is structured easily in telescopic motion and has a draw-out grip 5 like a rod antenna. Furthermore, a stopper 1 having a mount claw 1a for mount of a radio calling receiver 3 is provided in the middle of the metallic rod 2, and the radio calling receiver 3 is fitted by the stopper 1 so that the long side of the loop antenna is in parallel with the metallic rod 2.
