The STLP 9129 was especially designed for wideband immunity tests. The unique STLP 9129 is able to cover the entire frequency range from 70 MHz to 10 GHz with a typical isotropic farfield gain of 8.6 dBi with a ripple of less than +/- 2.3 dB only.

This unrivalled bandwidth was achieved by combining the both well proven antenna designs STLP 9128 D and the STLP 9149. The STLP 9129 does provide the optimum out of gain and field uniformity at the same time as well as both basic antennas do.
