It can also be used when inspecting areas for eavesdropping devices such as wirebound microphones. The detection of wires is effected in a passive mode. The detector measures the antenna effect of cables and wires which is due to ambient radio frequencies. The wire picks up the radio frequencies and is surrounded by a field of high frequency, which is detected andindicated by an audio alarm. The alarm intensity indicates the length of the antenna and the strength of the surrounding HF field. Even relatively short wires of less than 2 m length can be detected. Metal objects of compact shape or grids, which are not very sensible to high frequency, will show almost no interference while searching. If little ambient radio frequencies can be expected in the search area, a handheld transmitter can be used to improve detection results.
