Antenna, Loop

EM-6870 | 20 Hz – 100 kHz

The EM-6870 Loop Antenna obtains magnetic field measurements from 20 Hz – 100 kHz.

The antenna has a balanced faraday shield that reduces its response to electric fields to an insignificantly small amount, which results in practically pure magnetic field measurements.


The EM-6870 is suited for use in compliance testing to RE01/RE101 of MIL-STD-461, RE04 of MIL-STD-461A, CISPR recommendations plus other government and federal standards. The antenna is designed to work into a 50-ohm system and must be oriented for best sensitivity.



Frequency Range: 20 Hz-100 kHz
Impedance: Calibrated for use into 50 Ohms
Output Connector: Type BNC (shielded from electric fields)


Outside Diameter: 63.5 cm (25″)
Height: 68.6 cm (27″)
Weight: 500 g (1.1 lbs.)
