Abstract

PURPOSE:To prevent a change-over circuit from malfunctioning due to an ignition noise by sending control signals via a coaxial cable for antenna signal transmission by superposing while reducing transmission cables between a main antenna body and transmitter-receiver. CONSTITUTION:Control signals transmitted via coaxial cable 7 pass through only low-pass filter 6 to control switch 4. High-pass filter 5 stops control signals from passing, so that antenna signals and control signals can be separated from each other. Filter 5 is composed of a circuit that provides antenna signals with low impedance, and filter 6 is also composed of a circuit that provides switching control signals with low impedance.
