Concept Microwave has been designing, developing, and manufacturing high-quality passive and RF Microwave components in China for many years. Today, we will be reviewing their HFC4500 Combiner, which is a game-changer for all types of multi-operator contest stations, DXpeditions, and Field Day groups.

The HFC4500 Combiner allows for a single triband 20m/15m/10m antenna to be used by three stations running 1.5 kW simultaneously while fed with only one coaxial feedline. Just imagine the savings on maintenance, costs and space when a single antenna can be used instead of separate monoband Yagis on the 20m, 15m, and 10m bands.

The HFC4500 Combiner has many benefits and uses. It uses a high power Combiner, which connects to a triband 20m/15m/10m antenna and has ports for 20m, 15m, and 10m. Each of these ports much connects to a 4O3A Series S Bandpass Filter, which ensures optimal performance. Once you have this combiner, you have the flexibility to create triplexers, duplexers or you can use filters separately if you have monoband antennas.

When a 4O3A Triplexer System investment is analyzed, the savings in antennas, towers, feedlines, and maintenance 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 HFC4500 Combiner comes standard with a cooling fan, which ensures that the system will have optimal performance as it runs at peak power level. The HFC4500 without filters connected is compatible with all kinds of power divider, directional coupler, filter, combiner, duplexer, load & attenuator, isolator & circulator, and much more from Concept Microwave.

In summary, the HFC4500 Combiner is a high-quality product that is designed to provide optimal performance for multi-operator contest stations, DXpeditions, and Field Day groups. It allows for a single triband 20m/15m/10m antenna to be used by three stations running 1.5 kW simultaneously while fed with only one coaxial feedline. With the flexibility to create triplexers, duplexers, or use filters separately, the HFC4500 Combiner provides an excellent return on investment as it saves on maintenance, costs, and space.
