HFM2-20 - 2 x 20 kW HF Transmitter Multicouplers
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 15% frequency separation.
System losses are low, typically less than 0.2 dB and rejection of the adjacent transmitter greater than 30 dB.
