    ETS-Lindgren’s 3121D Dipole

    Introduction :

    ETS-Lindgren’s Model 3121D Tuned Dipole Antenna’s behavior approaches to the theoretically perfect half-wavelength resonant dipole.ETS-Lindgren has made select physical improvements to the original design assuring optimal performance and years of trouble-free use. The 3121D offers an accurate standard for precise EMI measurements including FCC and EN compliance testing, site attenuation as described in EN55022 and ANSI C63.4, and antenna calibration as described in ANSI C63.5.

    The model 3121D covers a frequency range of 30 MHz to 1 GHz and its behavior approaches to the theoretically perfect loss-less half-wavelength resonant dipole.

    Each 3121D Dipole is individually calibrated at 10 meters per ANSI C63.5, using the preferred three antenna method. All measurement equipment used is NIST traceable.

    These measurements are made without the use of attenuators, so antenna factors are a true presentation of actual performance. A printout of the calibration data of each antenna is included with the Manual and is also archived. Individual calibration and actual antenna factors are preferred over typical or theoretical factors and provide confidence of test data.
