PURPOSE
Locator for detecting devices of unauthorized information collection is used for detecting transceivers of unauthorized information collection by the resonance phenomenon in their antenna systems and supporting filter elements.
The Locator includes a generating-receiving unit, broadband antenna of 0,3-3 GHz, removable handle, a set of imitators of devices for unathorised information collection, power adaptor and charger for AC network, adaptor power cable, stereo headphones, microwave and USB cables, a strap and special software for data processing (on CD).
APPLICATION AREA
- during activities aimed at localizing radioñontrol devices or other operating units which have a radiocontrol channel

OPERATIONAL PRINCIPLE
The operational principle is analogous to the principle of non-linear locator. The main difference lies in the necessity to consider the possibility of missing the "target" due to the discrepancy in the polarization of the locator antenna and antenna of radiocontrol devices. In order to decrease the probability of target missing due to the antennas polarization discrepancy we would advise to change the nature of the locator antenna movement.
The operator conducts scanning activities in a zig-zag manner. Doing this, it is important to hold antenna tilted 45 degrees away from true vertical in one scanning direction and -45 decrees when moving in the opposite direction. It is vital to maintain the distance between the antenna and the concealed environment from 0,3 to 0,5 m.
When any device of unauthorized information collection is detected, a signal is produced. The closer the antenna gets to the detected device, the high is the tone of the signal.
