Flann’s OMT’s offer the high performance demanded by today’s communication systems, in which high polarization purity and high isolation are paramount.
The combination of low cross polar and high isolation characteristics provide optimum link performance.
Some examples of the models available are detailed in the table below.
Other models are available to suit many applications, frequency bands and power levels. Details on Request.
