QRH400 Quad Ridged Horn Antenna | 400 MHz – 6 GHz
with online calibration protocol and dataset
The QRH400 is a dual-polarized broadband horn antenna covering 400 MHz to 6 GHz, designed for large anechoic chambers and demanding EMC measurements. It delivers stable performance across a wide frequency range and is individually calibrated in our anechoic chamber, with calibration data available electronically on our website. Built-in spirit levels for both polarizations make it easy to align.
