WEB Code
E-Plane Bend
The published part-number guide identifies “WEB” as the E-bend configuration. Required A × B lengths are stated in millimetres and should be matched to the available installation envelope.
Double-Ridged Waveguide Bends
Waveguide bends are essential components in microwave engineering, designed to redirect electromagnetic waves along a desired path within a waveguide system. They facilitate the routing of signals through complex system geometries without significant loss, making them crucial for applications in radar, telecommunications, and satellite communications. Available in various angles and sizes, waveguide bends ensure efficient signal transmission and system integration.

*Catalog IL field: the current Dolph product table labels this column “IL (dB/m).” Because the published source does not define whether the value represents attenuation per unit length, bend loss or another catalog test convention, treat it as a catalog reference only. Confirm the applicable loss definition, test method and acceptance limit in the approved quotation or model drawing before final selection.
