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 conventional 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 above 30 dB. The HFHM2-2 series are suitable for 19″ rack mounting and do not require additional forced air cooling.

Models can be supplied with various notch widths and we will be pleased to advise on the most economical solution to your problems.
