Description
Cast Waveguide Bends
We stock many popular sizes of Cast Waveguide Bends. These are soldered/brazed onto waveguide to create a 30, 45, or 90 degree E or H bend in a waveguide system. (What does E and H mean?)
We stock Copper Alloy (Suitable for “Hard” Soldering/Brazing or “Soft” Soldering) and Aluminum Alloy (Suitable for Dip-Brazing or Furnace Brazing). All Castings are frequency compensated and have a VSWR generally less than 1.05 over the individual waveguide band.
