Abstract
PURPOSE:Loop antennas are fixed to a moving body so that reception levels above a fixed level are always maintained at portions other than the points of connection of leaking coaxial cables, whereby the passage of the moving body along the point of the connection that becomes a fixed point may be detected from the lowering of the level at the point of the connection even if no other equipment is provided on the ground.
