Couplers for CiRAY, N-SERIES and HOPS12T address a common issue present in many other line arrays – inconsistencies in horizontal directivity. It can be seen with many ‘traditional’ designs that the horizontal beam width varies in the MF / HF region. This is typically caused by the MF / HF driver placement, together with the use of more traditional waveguides and horns.
Couplers fundamentally solve this, by summing the energy from all transducers, to perform as a single source. This is achieved without any phase destruction, providing a perfectly coherent and uniform wavefront. They can be interchanged quickly and without tools to achieve various horizontal dispersions – narrow, wide, and asymmetric.
