STLP 9129 – Stacked Log. Periodic Antenna 

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. Main Application: Generation of definded high field strength levels for radiated immunity testing acc. IEC 61000-4-3.
