Description
Miter Bends E and H Plane with Flanges
PENN ENGINEERING offers a standard line of mitered waveguide bends for us in a waveguide system. Use these standard lengths to design your system, or give us your dimensions for a custom e-bend/h-bend combination and we will build them to your specifications.
Typical VSWR for standard mitered bends is 1.05:1 over the full frequency range.
Brass bends are Silver Plated per QQ-S-365D Class A, Aluminum Bends are Chem-filmed per MIL-C-5541E, and both are finished with PENN ENGINEERING’S Metallic Blue Paint.

Difference Between E and H Bends
How to Tell the Difference Between E and H Bends
The terms “E” and “H” plane refers to the electrical and magnetic planes of rectangular waveguide. The electrical plane or E-plane is the narrow plane of the waveguide and the magnetic plane or H-plane of the waveguide is the wide plane.
A simple way to remember this is that an E-bend is the “easy” way to bend waveguide and an H-bend is the “hard” way to bend waveguide.
