WR90 Waveguide Input Antenna (WI Series)
- Select
WI Series • X-Band (8.20 – 12.4 GHz)
FT-RF WR90 Waveguide Input Antenna
FT-RF WR90 Waveguide Input Antennas feature direct WR90 rectangular flange feeds across X-band spectrums (8.20 GHz to 12.4 GHz). Manufactured from high-grade aluminum, they deliver reliable gain calibration, high polarization purity, and stable radiation patterns for marine navigation, NEXRAD weather radar systems, and defense testing setups.
Built with precision electroformed/machined flares and standard UG-39/U cover flanges, WR90 input horns serve as high-efficiency feeds and reference antennas in radar systems, laboratory test benches, 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.
- Chamber Brackets: Low-reflection mounting plates.
