Electro-Metrics’ EM-6892 41” Active Vertical Antenna includes an amplifier that results in high sensitivity to the electric field in the frequency range of 10 kHz to 50 MHz.

The EM-6892 can easily be used with any 50-ohm receiving instrument requiring improved sensitivity. Its battery operation, which eliminates a control cable, adds to its simplified operation. The sealed lead-acid battery included is rechargeable overnight from both 110v and 220v 50/60 Hz power systems.

The EM-6892 provides 12 to 14dB improved sensitivity over the EM-6894 Passive Vertical Antenna in the range of 10 kHz to 10 MHz and 3 to 5 dB improved sensitivity or better up to 30 MHz.

Particularly helpful for automated testing is its flat antenna factor of +14 dB from 10 kHz to 20 MHz.
