The Millitech SGH-28-SP000 is a pyramidal horn antenna engineered as a standard gain reference source for Ka-band millimeter-wave systems. Electroformed construction delivers precise dimensions and reproducible electrical characteristics across 26.5–40 GHz, making it suitable for antenna gain measurements, feed applications, and radiation monitoring. The antenna operates at 24 dBi typical midband gain with 25° beamwidth and supports horizontal, vertical, and circular polarization when equipped with a polarizer.
