This 12" Broadband Loop Antenna with preamplifier is an excellent solution for magnetic field testing.
The SAS-563B Active Loop antenna is shielded against the electric component by enclosing the conducting loop within an all-metal shield. This ensures that it is just the magnetic component of the radiated energy that is responsible for producing an output voltage. 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 the "E" field separately with a high impedance monopole antenna.
