Coax-to-Waveguide Adapters

Coax-to-Waveguide Adapters
Model: ANT-CWA

Our coax-to-waveguide adapters offer a convenient transition between waveguide and coaxial transmission lines. Coverage from 350 MHz to 90 GHz is available in commonly used waveguide bands. Each unit has a waveguide flange interface and a connector. All flange interfaces are compatible with NSI-MI standard gain horns and many of our near-field probes and feeds.
