WR284 Waveguide Input Antenna (WI Series)
- Select
WI Series • S-Band (2.60 – 3.95 GHz)
FT-RF WR284 Waveguide Horn Antenna
FT-RF WR284 Waveguide Horn antennas are precision passive pyramidal devices featuring direct WR284 rectangular flange feeds across S-band spectrums (2.60 GHz to 3.95 GHz). Manufactured from high-grade aluminum, they deliver reliable gain calibration and stable linear polarization for radar, Wi-Fi 2.4/3.5GHz, and microwave testing.
Built with heavy-duty structural aluminum walls and standard CPR284F cover flanges, WR284 input horns serve as high-efficiency feeds and reference antennas in NEXRAD weather radars, airport surveillance systems, and anechoic chambers.
🛠️ Engineering & Customization Options
Tailored structural designs and custom bracket options:
- Custom Dimensions: Tailored flare lengths & holes.
- Phase-Matched Sets: Gain and phase matched pairs.
