Operating experience of wire wave sensors shows that on efficiency of their application essential agency renders change of conditions of medium of functioning. The principle of act of wire wave sensors is based on registration of change of the electromagnetic field created in space by antenna system, called by affecting of external factors (the infringer, handicapes). In a regime on duty in antenna system the regime close to a regime of a travelling wave is installed. Thus the threshold device reacts on change of amplitude of a sounding signal on a receiver en-try.
