The Narda EF 1891 NBM E-Field Probe detects electric fields from 3 MHz to 18 GHz, covering the fields generated by broadcasting, telecoms, and radar. The dynamic range from 0.6 V/m up to 1,000 V/m (64 dB) makes the Narda EF 1891 NBM E-Field-Probe ideal for measuring exposure in both the general public and the occupational environment. The probe contains three orthogonally arranged dipoles with detector diodes. The three voltages, corresponding to the spatial components, are available individually at the probe output. The NBM basic unit calculates the resulting isotropic field strength. The probe is designed with mechanical and electrical properties ideal for field use. The probe head is made of foam material to provide effective protection for the sensors, while having excellent RF characteristics. The electric destruction limit of 1,600 V/m for continuous wave signals is several times higher than any of the human safety limit values.

The Narda EF 1891 is compatible with the Narda NBM-550 Broadband Field Meter.
