Advantages over analogues: Antennas AIM counterparts do not have.

The development stage readiness: Introduced in production

Description of the development:
()
An important element in the protection of information from mechanical intelligence is instrumental monitoring of the effectiveness of protection. This is especially true when working in the field of low-frequency magnetic fields (NMP) with high penetrating power. When performing measurements with the antenna loop condition must be provided: d> = D, where d - the distance from the radiation source to the antenna, and D - aperture antennas. Antenna with a small aperture allows more accurately determine its distance to the radiation source, which is essential in the measurements in the near field. Compact antenna allows measurements are close enough to the source. We have developed point-frame active antenna series PAM (hereinafter - the antenna PAM), are characterized by high sensitivity and wide dynamic range. New circuit solutions allow to reduce the diameter of a frame with 250 mm 0.8 - 1 mm, and accordingly, reduce the aperture area of ??the antenna is about 1000 times, making the loop antenna in a compact remote probe. To cover the private range of 5 Hz ... 30 MHz (23 Aktava) uses three antennas modification: AIM 0.005 AIM LF 200; AIM HF 0.1-30.
