Rev : B | Rev date : 18 Apr 2024

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.

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.

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.

FEATURES / BENEFITS
