Introduction：
VULP 9118 D Special is a log-periodic antenna manufactured by Schwarzbeck (Germany) and distributed by EUTTEST (Shenzhen). The antenna is available from 80MHz to 1800MHz, and the specially customized special log-periodic antenna is capable of inputting up to 1kW of power over the full frequency range, which allows EMC testers to use the antenna for immunity testing of DUTs with high radiated field strengths.
The Special version has the same gain as the VULP 9118 D. The difference is that the Special version collapses the longest antenna oscillator at the rear end, which prevents the antenna from being too long and touching the darkroom ground plane when switching antenna polarization.
