WR137 Waveguide Input Antenna (WI Series)
- Select
WI Series • C-Band (5.85 – 8.20 GHz)
FT-RF WR137 Waveguide Input Antenna
FT-RF WR137 Waveguide Input Antennas feature direct WR137 rectangular flange feeds across C-band spectrums (5.85 GHz to 8.20 GHz). Manufactured from high-grade aluminum, they deliver reliable gain calibration and stable linear polarization for C-band satellite uplink/downlink transponders, radar systems, and microwave test benches.
Built with precision electroformed/machined flares and standard CPR137G or FDP70 cover flanges, WR137 input horns serve as high-efficiency feeds and reference antennas in satellite ground stations 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.
