ABSTRACT:
An electromagnetic noise source locator is comprised of an audio amplifier which is connected to drive a speaker and to which is connected at the input a series circuit that includes a very small antenna loop of area less than 1 in.sup.2, a diode and a capacitor. This apparatus responds only to bursts of radiated energy and furthermore responds only to such bursts having frequency components over about 1 GHz. It is therefore particularly suitable for the selective sensing and location of sparking gaps as may occur on power lines.
