FT-RF WR42 Waveguide Input Antenna is a precision-engineered K-Band waveguide input antenna (18.0 GHz to 26.5 GHz) designed for seamless integration into high-frequency waveguide systems. With an optimized input structure, it provides excellent signal coupling and stable radiation characteristics for radar systems, satellite communications, and high-precision measurement systems.

Constructed from high-precision CNC machined aluminum alloys, this antenna guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness across the entire frequency band, ensuring reliable and repeatable measurement results in laboratory environments.
