Flexi RF provides a specialized line of horn antennas for high-performance transmission and reception in the microwave and millimeter wave spectrums. Our horn antenna array comprises conventional-gain and wide-band ridged versions, designed to provide consistent gain, low VSWR, and predictable emission patterns. These antennas are critical for anechoic chamber testing, antenna calibration, field-strength testing, and satellite communication links. Flexi RF's horn antennas are made of premium-grade aluminum or copper and have precision-machined surfaces to reduce side-lobe levels and maximize front-to-back ratios. Our inventory covers a wide range of frequency bands from 1 GHz to 110 GHz and uses either standard waveguide interfaces or integrated coaxial connectors such as SMA, 2.92mm, or 2.4mm. Whether you are conducting EMI/EMC testing or developing radar systems, a Flexi RF horn antenna provides the mechanical durability and electrical accuracy required for high-stakes electromagnetic research.
