NSI-MI coax to waveguide adapters (ANT-CWA) provide a simple and convenient way to connect between a waveguide and coaxial transmission line. Adapter coverage is available from 350 MHz to 70 GHz in commonly used waveguide bands. These adapters are precision manufactured and have low VSWR. ANT-CWA adapters are designed to fit NSI-MI's Standard Gain Horns (ANT-SGH) and many of our near-field probes and feeds.
