Description & Specification
WR284 S Band Waveguide Horn Antenna (Model: HS-284-UDR-20A-NF)
2.6 - 3.95 GHz | 20 dBi High Gain | N-Female Connector
The HS-284-UDR-20A-NF is a high-performance WR284 Waveguide Horn Antenna assembly manufactured by FT-RF in Taiwan. Designed for S Band applications ranging from 2.6 GHz to 3.95 GHz, this system combines a high-gain horn (WI-284-UDR-20) with a precision coaxial adapter (WC-284-UDR-NF). With a robust aluminum body and stainless steel N-Female connector, it delivers a substantial 20 dBi gain and handles power up to 300 Watts. The unit features a low VSWR of 1.25, making it ideal for long-range communications, radar systems, and laboratory testing.
