PLA30M Overview
The PLA30M electrostatic shielded loop antenna is typically used for shielding effectiveness testing per IEEE 299, MIL-STD 285 and NSA 65-6 as well as many other test standards. This passive 12" (30cm) diameter loop antenna is shielded against the electric component by enclosing the conducting loop within an all-metal shield. This balanced faraday shield ensures that it is producing (or measuring) just the magnetic component of the radiated energy. Due to the relatively long wavelengths in this band, and the typical test distance from the source, the 377 Ohm relationship to the E-field will not hold true and you may have to measure (or produce) the "E" field separately with a high impedance monopole antenna.
