:: HFM2-5 - 2 x 5 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.
System losses are low, typically less than 0.2 dB and rejection of the adjacent transmitter greater than 30 dB.
