Schwarzbeck STLP 9129 Stacked Logarithmic Periodic Antenna

The Schwarzbeck STLP 9129 was especially designed for wideband immunity tests. The unique STLP 9129 is able to cover the entire frequency range from 80 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

For mechanical reasons the antenna comes with an ultra-low loss radome cover to protect the radiating elements at the antenna tip.

By default, the STLP 9129 is equipped with fast links for the rear radiating elements, which are responsible for the low frequency range between 70 MHz and 180 MHz. These unique fast links allow the quick disassembly of the antenna within less than a minute into five handling-friendly parts. The rear radiating elements can be omitted if there is no need to cover the frequency range from 70 MHz to 180 MHz.

The antenna main structure comes with support rods on rubber feet for safe placement on the ground when not in use.

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