System for controlling the movement of an animal

摘要: A system for controlling the movement of an animal relative to area is provided having a signal transmitter with transmitting antenna associated said area. loop wire serves as and defines boundary An electronic receiver carried by responsive produced producing control output, such annoying tone or electrical shock, whenever moves into vicinity antenna. The has first second orthogonal receiving antennas Each receives respective component transmitted signal. Selection circuitry selects which components greater magnitude produces actuating output identify component. Switch from each antennas. switch responds selection magnitude. Control selected circuit As such, continuously best reception produce output.
