Note: The SP1 electrostatic panel operates as a dipole, radiating energy forward and rearward. Since the anechoic chamber absorbs all rearward-directed energy at the frequencies the panel operates, that output does not get reflected in the sensitivity measurement, which is therefore lower in our measurements than in reality.
