The path between the MPX encoder and the transmitter, as well as the unbalanced link, are the two main factors that damage the MPX signal to noise ratio. This noise is due to the true difference of earth equipotential.

Thanks to the transformer galvanic insulation, SYM100 cancels the grounding loops, considerably improving signal to noise ratio.

Inputs/outputs on BNC, and the usable frequency largely exceed the maximum bandwidth of MPX signal.
