Micro-Twists

A range of micro twists are ideal for applications where space is at a premium.

The machined micro twist is ideal for applications needing a 90 degree twist in polarisation in a small space. It is particularly useful at lower frequencies where the saving in weight and space can be significant. The machined twist typically covers half a waveguide band. Please contact our sales team for ordering information.

Micro-Twists

A range of micro twists are ideal for applications where space is at a premium.

The machined micro twist is ideal for applications needing a 90 degree twist in polarisation in a small space. It is particularly useful at lower frequencies where the saving in weight and space can be significant. The machined twist typically covers half a waveguide band.
