Precision Straights

A range of standard length waveguide straights in a variety of materials. The high performance is based on the use of selected, sized, tube, careful assembly and selective tuning where necessary.

Precision Bends

The precision bends have been designed to offer the optimum performance based on an average length and bend radius. All bends are precisely assembled to ensure the highest performance.

Compact Bends

A set of specifications has been provided to offer the minimum radius bend available for both "E" and “H” plane bends in the respective frequency range.

Precision Twists.

The precision twists have been designed and precisely assembled to offer the optimum performance based on an average length and twist angle. They are available in clockwise and anticlockwise orientations.
