Elliptical Waveguide

The Radio Frequency Systems organization is the originator and designer of continuous seam welded corrugated transmission lines. FLEXWELL is RFS's brand name for the highest quality, best performing, and most reliable elliptical waveguide in the industry.

FLEXWELL waveguides are available in a wide selection of frequency bands throughout the 2 GHz to 23 GHz microwave bands. They are equivalent in sizes to rectangular waveguide WR340 through WR42.

Two versions of FLEXWELL elliptical waveguide are offered: FLEXWELL "standard" waveguide and low VSWR "premium" waveguide with tunable connectors. Standard and premium waveguide differ only in testing and guaranteed attainable VSWR. FLEXWELL "standard" waveguide is recommended for low and medium capacity radio relay systems, while FLEXWELL "premium" elliptical waveguide assemblies with tunable connectors are recommended for high capacity radio systems.

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.
