The YD-QRHA218-1-S-K four‑ridge closed‑type horn antenna operates over a frequency range of 2 GHz to 18 GHz. It delivers a nominal gain of 15 dB. At the center frequency, the typical 3-dB beamwidth is 29.9° in the E‑plane and 23.9° in the H‑plane. The input connector is an SMA‑K coaxial interface. This antenna supports dual linear polarization; by incorporating a 90° hybrid coupler at its two ports, it can also achieve dual circular polarization.
