HF High Power Combiner

Very useful for extending any tribander system to be used as three single antennas, at the same time.


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 1.5 kW Simultaneously.


HF High Power Combiner

 

For 20M-15M-10M


Truly a "game changer" for SO2R and multi-operator contest stations, DXpeditions and Field Day groups. The 4O3A Signature Series Triplexer System eliminates the need for separate monoband Yagis on the 20m, 15m and 10m bands. Three operators, three stations and three amps but only one feedline and one antenna!

The 4O3A HF Triplexer Systems uses a high power Combiner, which connects to a triband 20m/15m/10m antenna, such as the great new Force 12 XR3 Multi-Mono Yagi, and has ports for 20m, 15m and 10m. Each of these ports much be connected to a 4O3A Series S Bandpass Filter, the Combiner is not intended to be used by it self.


When analyzing a 4O3A Triplexer System investment bear in mind the savings in antennas, towers, feedlines and maintenance that will accrue. It's worth noting that Mr. 4O3A himself, Ranko Boca, replaced many of the rotatable monoband Yagis at his famed mountaintop contest station with tribanders set in fixed directions feeding Triplexer Systems. When you make north of 50,000 contest QSOs a year you learn what works (and what doesn't)

The 4O3A HF Triplexer Systems uses a high power Combiner, which connects to a triband 20m/15m/10m antenna, such as the great new Force 12 XR3 Multi-Mono Yagi, and has ports for 20m, 15m and 10m. Each of these ports much be connected to a 4O3A Series S Bandpass Filter, the Combiner is not intended to be used by itself.

Now standard with cooing fan.

 

Once you have combiner, system is flexible, as you can create triplexer, diplexer, or use filters separately if you have monoband antennas
