Product Description
Main Parameters
Structural parameters

YD-HA4-20 is a standard gain horn antenna that operates from 170 GHz to 260 GHz. The antenna offers 20 dB nominal gain. At the center frequency, the typical 3 dB beamwidth is 14.7° on the E-plane and 15.7° on the H-plane. The antenna supports linearly polarized radiation. The input interface is WR-04 waveguide with UG-387/U anti‑cocking flange. The antenna uses an integral wire-cutting process and is fully gold-plated to ensure excellent electrical performance.
