FLEXWELL® elliptical waveguide is constructed of longitudinally continuous seam welded, highly conductive copper tube, corrugated and precision formed into an elliptical cross section. It is
manufactured in continuous lengths using a special seam welding process developed by the RFS
organization.
The corrugation design achieves high transverse stability, flexibility and crush strength for superior
handling and forming at an installation. The inherent strength and flexibility of FLEXWELL waveguide
allows on location, a continuous length of waveguide to be run directly from a tower-mounted
antenna to the equipment building, eliminating flange joint discontinuities and the use of bends,
twists and flex sections associated with a rigid rectangular waveguide system. Because of its
flexibility, FLEXWELL elliptical waveguide can be easily transported to an installation site in coils or
on reels and then uncoiled as required during installation.
FLEXWELL elliptical waveguide has set an industry standard for excellent electrical performance.
Each waveguide has been carefully designed for low loss and low VSWR in specific frequency
bands. For optimum system performance, there is no substitute for FLEXWELL waveguide.
As part of the RFS manufacturing process, all elliptical waveguides undergo several different
electrical tests. Prior to shipping, every length is 100% tested again for input VSWR, and undergoes
a twenty-four hour pressure test. This additional testing is performed to guarantee conformance with
published specifications and to avoid any problems in the field.
A FLEXWELL elliptical waveguide feeder requires less planning and reduces installation costs
when compared to a feeder system using a rigid rectangular waveguide. FLEXWELL waveguide is
available cut to length with factory attached connectors or in continuous lengths for termination in the
field.
