Waveguide tubing is used to transmit and receive radio waves, much like a gun barrel is used to fire shells. As with most engineering products there are adequate products and there are superior products.

Our EVERED operation is renowned world-wide for high precision waveguide. EVERED manufacture and hold inventory of the widest range of waveguide sizes and alloys as well as responding to client requests whether for special alloys, wall thickness, or reduced height products – all manufactured to the world’s highest tolerances.

The table shows the standard range of waveguide tubing.
