QRH300 Quad Ridged Horn Antenna | 300 MHz – 4.5 GHz
with online calibration protocol and dataset
The QRH300 is a dual-polarized broadband horn antenna operating from 300 MHz to 4.5 GHz, ideal for EMC testing and wideband measurements in large chambers. It features integrated spirit levels for easy alignment in both polarizations. Each antenna is individually calibrated in our anechoic chamber, with calibration data available electronically on our website.
