FT-RF WR51 Waveguide Input Antenna is a precision-engineered Ku/K-Band waveguide input antenna (15.0 GHz to 22.0 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 airborne 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.
