Antenna, Active Loop

EM-6876 | 9 kHz – 30 MHz

The Electro-Metrics EM-6876 Active Loop Antenna is used with EMI Receivers and Spectrum Analyzers with 50 ohm input and covers the frequency range of 9 kHz to 30 MHz.

The EM-6876’s internal active circuitry, which is battery powered, equalizes the frequency response of the loop antenna so that the EM-6876 has a relatively constant antenna factor across the 9 kHz to 30 MHz range.


The EM-6876 is specifically designed to perform VDE 0871 LIMIT B, FCC part 15 and 18 testing plus SAE and other government and commercial standards.
