RFD-5 is a highly sensitive wide-band radio frequency detector with large dynamic range and enormous frequency range. RFD-5 functionality is optimized for professional detection and localization of radio listening devices.
Current radio-electronics offers a number of eavesdropping systems which cannot be detected before their operative activation. There are two basic solutions to prevent eavesdropping: electronic sweeping and permanent protection. RFD-5 is designed for professional electronic sweeping and additionally it allows even a non-specialist to achieve basic permanent protection.
RFD-5 is light compact device built in a mechanically robust metal box. Its main features are:
* High sensitivity and dynamic range
