The triplexer allows you to use one antenna simultaneously on three bands at the same time. Three radios transmitting to the same antenna at the same time via one coax cable.

This is a complete revolution, which makes one three-bands antenna work like three completely independent monoband antennas. By using the triplexer, you will avoid the need to build more masts and antennas.

Triplexers are used not only on large contest stations, where there is no space to build more tall masts, but also on small Low Power stations, where the operator has only one or two small antennas.

Just think, you would like to have access to three independent directions on the 10m, 15m and 20m bands at the same time. In the classic approach, this would require as many as 9 monoband antennas. With the use of triplexers and tribander antennas, all you need is 3 antennas and you will achieve the same result!

Do you think you need large tribanders to use a triplexer?
Not at all, all you need is a small three-band Vertical or HexBeam. This allows you to improve your station with triplexer.

When using a triplexer, it is necessary to use low-power bandpass filters for each band (link below).
