Prior to the introduction of MIL-STD-461F it was possible to perform RF susceptibility tests using currently available antennas on 30-200MHz. MIL-STD-461F was introduced to address the deficiencies of previous RF susceptibility standards and thus made it extremely difficult and expensive to achieve successful testing using existing antenna technologies. Because the SY3-EMC Yagi is a High-Q, adjustable antenna that has very high efficiency, a wide beam-width and excellent harmonic rejection, it makes susceptibility testing to the specifications of now MIL-STD-461G and RS-103, a reality.
