Dolph Microwave waveguide tube manufacturer specializes in the production of extremely precise waveguides from WR2300 to WR10 in most alloys, including Aluminum, OFHC (aka OFE or OF-DLP) Copper, Bronze, Invar, Stainless Steel, Coin Silver, and more. Standard waveguide lengths are 12 ft. and we can cut waveguide to your dimensions on request. We also offer special sizes such as Half-Height, Double-Ridge, and Heavy-Walls and we can quote you on custom sizes of Rectangular Waveguide Tubing. For more information, please contact us and discuss your needs with our sales engineer.
