FT-RF WR19 Waveguide Input Antennas feature direct WR19 rectangular flange feeds across U-Band spectrums (40.0 GHz to 60.0 GHz). Crafted from high-purity electroformed copper and aluminum alloys, these broadband passive horns offer exceptional gain stability, low cross-polarization, and reliable calibration performance for millimeter-wave test benches.

Built with precision electroformed/machined flares and standard FUGP500 cover flanges, WR19 input horns serve as reliable reference standards and high-efficiency feeds in satellite terminals and radar systems.
