Aaronia MDF 50400X

Active Tracking Antenna (500kHz - 400MHz, active with 40dB Preamplifier)
SKU: AA-694
Product Description

The Aaronia MDF 50400X is a broadband, active magnetic field tracking antenna, suitable for signal tracking and field strength measurements. With high directionality of the antenna, the MDF is ideally suited for signal direction finding.

In contrast to the passive version, the MDF 50400X comes with directly attached 40dB preamplifier. The thus reached extremely high antenna gain allows the measurement of ultra-weak signals.

The preamplifier of the antenna can be operated by an internal battery or by the included USB AC adapter. The battery time is approx. 3-4 hours. The USB connection allows to read out the calibration data of the preamplifier, which are stored in the internal EEPROM and therefore can not be lost.
