The OBH-180400-20 Dual-Ridged Horn Antenna, introduced by RFecho, is a testament to cutting-edge advancements in the RF landscape. This antenna is renowned for its broadband operation, covering a frequency spectrum from 18GHz to 40GHz, encompassing the pivotal Ka-band. It seamlessly integrates consistent gain performance, minimized return loss/VSWR, and an expansive bandwidth. The antenna's distinct design effectively curtails the excitation of undesired higher-order modes in the aperture, guaranteeing a uniform smooth radiation pattern across its entire operational bandwidth. While it packs a punch in terms of capabilities, it remains lightweight at just 250g, facilitating ease of handling and mounting on antenna towers, tripods, or other supports. Its solid mechanical structure combined with precision engineering ensures consistent performance across diverse applications. Moreover, it is equipped with a mounting flange and an integrated coaxial transition featuring a high-precision connector.
