2 x 20 kW Multicouplers 2017-01-11T09:31:45+00:00

Transmitter multicouplers utilising low loss filter networks enable multiple transmitters to work into a common antenna. Computer aided design techniques provide optimum performance from passive LC circuits which allows transmitters to work at close separations of 40%, 20% or optionally 15%.

System losses are low, typically less than 0.3 dB and rejection of the adjacent transmitter greater than 30 dB.
