Waveguide Tube
A waveguide tube is a hollow metallic conduit used to direct and carry electromagnetic waves in microwave, radio frequency, and other communication systems. It supports efficient signal transmission over a range of frequencies, providing a controlled path with minimal loss and dispersion.

Custom Length
Up to 3000 mm*
Materials
Aluminum / Copper
Wall Options
Standard / Thin / Heavy
Rectangular Waveguide Tubing
Select the Waveguide Size, Material and Cut Length
Use the operating band to select the WR family, then define the tube material, wall condition, finished length and dimensional requirements. Standard catalog lengths are 2000 mm; cut-to-length supply and longer sections are confirmed by size and quotation.
Electrical Selection
Match the WR Family to the Required Band
The catalog covers standard rectangular waveguide sizes from WR2300 through WR10. Model selection should be based on the system operating band and the required mating interface.
Mechanical Selection
Define Material, Wall and Finished Length
Aluminum is listed across the lower-frequency large-size range, while copper is used across the smaller millimeter-wave sizes. Several intermediate sizes are listed with aluminum or copper options.
