WAVEGUIDE-TO-COAX ADAPTORS

A complete set of standard waveguide-to-coax adaptors are available from Seavey Engineering. They may be utilized in any microwave test setup. They also may be added to standard gain horns as an option to provide a coaxial connector. Both broadwall and end-on styles are available in most frequency bands. All adaptors feature excellent VSWR and have stable characteristics. High power handling adaptors are also available in large waveguide sizes.
