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 MDF antenna provides a very high accuracy over a wide frequency range.
This feature allows the use of the MDF as a highly accurate field strength meter in conjunction with power meter or spectrum analyzer.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.
