    Isotropic Antenna for EMF Measurement
    INTRODUCTION
    The AT3000 device contains three passive, independent, Max applicable field strength: > 500 V/m (1 dB
    orthogonal antennas, designed and built in Calzavara - compression point)
    Clampco Sistemi NIRLab laboratory. If used with the ferrite
    bead coaxial cable supplied it allows reliable measurement of Isotropic measurement uncertainty
    radio-frequency electric fields which have an environmental ± 3.0 dB from 30 MHz to 85 MHz
    impact in the vast majority of practical cases. The three ± 2.0 dB from 85 MHz to 110 MHz
    orthogonal antennas are framed in the black spherical ± 1.5 dB from 110 MHz to 2.1 GHz
    polystyrene radome. The axis selection is accomplished by an ± 1.0 dB from 2.1 GHz to 3 GHz
    internal RF electronic switch remotely controlled by a cable Note: antenna in vertical position with at least 1.5 meter
    connected to the antenna pigtail. The special ferritized cable ferritized cable for any field incidence direction
    supplied with the antenna and it is composed by the RF cable
    and the axis selection cable.
