The OBH-180500-15 Dual-Ridged Horn Antenna, presented by RFecho, stands out as a remarkable innovation in the RF domain. This antenna boasts its broadband operation capabilities, spanning a frequency range from 18GHz to 50GHz. It amalgamates stable gain performance, low return loss/VSWR, and a wide bandwidth. The antenna's unique design effectively suppresses the excitation of unwanted higher-order modes in the aperture, ensuring a well-defined smooth radiation pattern throughout its operational bandwidth. Despite its robust capabilities, it's designed to be lightweight, weighing merely 200g, making it exceptionally convenient for handling and installation on antenna towers, tripods, or supports. Its sturdy mechanical design and precision machining ensure repeatability and reliability across various applications. Additionally, it comes equipped with a mounting flange, an integrated coaxial transition with a high-precision connector, and an optional protective radome for outdoor installations.
