    1.0 Introduction The ETS-Lindgren 6500 Series Loop Antennas include both active and passive antennas. Loop antennas provide a wide range of magnetic field testing. Some models include active electronics for amplification and impedance matching, consistent linear antenna factors, and signal attenuation. Most include a balanced Faraday shield to reduce response to E-fields for pure magnetic field measurements.

    7.0 Radiation Pattern The 6500 Series Loop Antennas are electrically small loops (size is small in wavelengths), giving them identically-shaped radiation patterns. Each loop operates at a frequency under 30 MHz. At 30 Hz the wavelength is 10 m; the largest loops have a circumference of 1.88 m (C=πD), which is much smaller than the wavelength.
