WI Series • K-Band (18.0 – 26.5 GHz)
FT-RF WR42 Waveguide Input Antenna
FT-RF WR42 Waveguide Input Antenna is engineered for high-precision K-Band microwave systems operating across 18.0 to 26.5 GHz. Featuring a direct UG-595/U standard waveguide flange feed, it provides exceptionally low insertion loss, high power handling, and clean radiation patterns for chamber calibration and antenna measurement ranges.
Precision CNC machined from high-grade passivated aluminum and copper alloy, this horn delivers outstanding gain flatness and cross-polarization discrimination. It serves as an optimal feed and reference antenna for 5G mmWave backhaul, satellite transceivers, and radar test benches.
🛠️ Engineering & Customization Options
Tailored structural designs and custom bracket fabrication for your setup:
- Custom Gain: 10 dBi, 15 dBi, 20 dBi, and 25 dBi options.
