The SBA9113B antenna is based on the SBA 9113 antenna, adding a balum to extend the low end of the frequency range to 80MHz. SBA 9113B can be used as a frequency field detector in immunity testing, for example, in combination with a spectrum analyzer or EMI receiver in accordance with IEC 61000-4-3. Depending on the frequency, the field strength of 1V/m is between 60-95 dBμV in the receiver. Although the SBA 9113B can be directly connected to the receiver, the field strength can reach 30V/m, it is recommended to use a fixed attenuator on the antenna connector, which can achieve better impedance matching and test accuracy and a wider measurement range.

       The main purpose of the microwave biconical antenna is to evaluate the test site, measure the field strength (frequency selection) and generate a specific field strength (such as ERP or EIRP). Due to its broadband characteristics, it is not necessary to replace the antenna as frequently as a half-wave dipole antenna, thereby saving measurement time. Microwave biconical antennas allow continuous frequency sweeps to be performed across the entire frequency range. Due to its similar pattern, fixed phase center and high power handling capability to dipole antennas, SBA 9113B can replace half-wave dipole antennas in many occasions.

       SBA 9113B is not suitable for very low limit radiation emission tests. Horn and logarithmic antennas are more suitable for this purpose due to their better antenna coefficients. A typical application of SBA 9113B is to determine the field strength exposure near the base station in the GSM frequency band.
