QRH18R Quad Ridged Horn Antenna | 1 GHz – 18 GHz
with online calibration protocol and dataset
Specially developed for EMC/EMI testing. This dual-polarized antenna operates from 1 GHz up to 18 GHz and, with a proper 90deg hybrid coupler, can obtain circular polarization (LHCP or RHCP). Thanks to radome, this antenna is suitable for outdoor applications. It is equipped with the standard L-shape holder, hermetically sealed, and a Gore air vent. Each unit is individually calibrated in our anechoic chamber, with full measurement data available through the Antenna Portal.
