These high-power (4,500 W ICAS) Band Pass Filters are to be fitted on the output side of your linear amplifier, filtering out not only harmonics but also broadband noise from the PA.

The 4O3A High Power HF Triplexer System Enables A Single Triband 20m/15m/10m Antenna (typically a Yagi) Fed With A Single Coaxial Feedline,To Be Used By Three Stations Running 4.5 kW simultaneously.

In order to meet the different needs and various setups of big stations we decided to put flexibility in to the foreground of our design. Instead of designing a simple Quadriplexer with four fixed band outputs we designed our Combiner QPXC-8, as an addition to the existing Triplexer System.
