FT-RF WR1800 Waveguide Adapter is a precision-engineered Sub-1GHz / VHF Band waveguide-to-coaxial adapter (410 MHz to 620 MHz) designed to seamlessly connect WR1800 waveguide systems with 7/16 DIN or N-Type coaxial cables and instruments. With ultra-low VSWR and minimal insertion loss, it provides accurate signal coupling for low-frequency EMC radiated emissions testing, defense broadcast calibration, and high-precision measurements.

Constructed from high-precision CNC machined aluminum alloys, this adapter 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.
