The QRH20ECR is a broadband horn antenna operating from 1.7 GHz to 20 GHz for broadband communication and field measurement. It features our 3D-printed antenna lens – a technology patented in the USA – which increases gain in a lightweight, compact design. The antenna is encased in a rugged, weather-resistant IP65 radome, and each unit is individually calibrated in our anechoic chamber.
