Abstract

PURPOSE:To protect against an abnormal voltage to be caused by the thunder or the mixed contact with a power distribution line without reducing a high frequency characteristic by providing separately first and second circuit patterns, enlarging dielectric strength, connecting a high voltage proof capacitor between first and second circuit patterns and compensating a high frequency characteristic. CONSTITUTION:Between a circuit pattern 22 and a circuit pattern 23, at least one capacitor 35 or above is connected. The capacitor 35 compensates the high frequency characteristic, and usually 1-4 capacitors are used in accordance with the difference of the constitution of the circuit pattern 22 and the circuit pattern 23. The capacitor 35, in which has the value of sufficient dielectric strength due to the circuit pattern 22 and the circuit pattern 23, is used. Since the circuit pattern 22 to connect the central conductor of a coaxial cable and the circuit pattern 23 to connect the earth conductor of the coaxial cable are separately provided, the sufficient dielectric strength can be obtained, Thus, the sufficient protection to the abnormal voltage due to the thunder or mixed contact with the power distribution line can be executed.
