Flat vibrator 420NJ., linearly polarized, its shape is flat, it is suitable for SBA9113 balun transformer, and it also matches SBA9113B and SBA9113 simplified version. Effective anti-jamming test can be carried out at close range.

  In all current anti-jamming tests, the typical test distance is 1 meter to 3 meters, which requires expensive power amplifiers. A variety of test investigations on mobile phones and handheld radio transmitters have shown that such devices can generate high field strengths of about 100V/m with very little power. However, the existing anti-jamming test method is very laborious to achieve such high field strength as described above.

  Thanks to the special shape of 420NJ, it can produce a great bandwidth, and it is also very close to the surface of the object to be measured, generally 5mm. This is an economical way to generate extremely high field strengths, requiring only moderate power levels, such as 10 to 20 watts. Due to the large bandwidth of the radiating element, no antenna adjustment is required, and fast broadband testing can be performed. Therefore, no other equipment is needed, and even special frequencies in remote villages can be measured.

  This equipment is typically used to test components in the automotive electronics industry, medical, scientific or aerospace fields, and is aimed at handheld radio transmitters. Usually, the surface of the measured object is divided into approximately 10 cm grids, and the antenna is emitted under the required strong field to observe whether the measured object is sensitive. The typical antenna is 5-50mm away from the surface of the object under test, depending on the size of the respective gasket.
