Description

The PE-W90TF005-24 is part of Pasternack’s family of flexible, twistable waveguides which operates in the 8.2 to 12.4 GHz

range. The waveguide body is made of a helically wound silver coated brass strip. It can be twisted and/or bent in both the

E and H planes without impairing VSWR or attenuation. The waveguide is covered by a neoprene jacket which protects the

waveguide, provides mechanical support and allows the waveguide to be pressurized.
