Magnetic Direction Finder Aaronia MDF 9400
The Aaronia MDF 9400 is a broadband magnetic field tracking antenna, suitable for signal tracking and field strength measurements. The special conversion factor of the MDF, in conjunction with a Power Meter showing dBm values, gives a direct dBA/m display with correct sign (power meter function).

Thanks to the high directionality of the antenna, the MDF is ideally suited for signal direction finding.

For measurements with highest sensitivity we recommend to use the active version, e.g. the MDF 50400X
