QRH18EC Quad Ridged Horn Antenna | 1 GHz – 18 GHz
with online calibration protocol and dataset
The QRH18EC is a broadband horn antenna operating from 1 GHz to 18 GHz, with built-in spirit levels for precise alignment. It features our 3D-printed antenna lens – a technology patented in the USA – which brings the maximum gain to 23 dBi without compromising bandwidth. Each unit is individually calibrated in our anechoic chamber, and test data is digitally available via QR code.
