Flann full-band OMT’s offer the high performance demanded by today’s communication systems, in which good polarisation purity and isolation are paramount. These instruments have two rectangular ports on adjacent faces, and a common circular port.
The OMT is a bi-directional device which allows signals to be sent from, or received at, the rectangular ports via an antenna supporting dual polarisation (at the common port). It can also be used to separate the vertical and horizontal components of a circularly polarised or elliptically-polarised wave, or to combine two signals to transmit a circularly or elliptically-polarised wave from a suitable horn antenna.
The models currently available are detailed in the table below. Designs can be adapted to custom output diameters
