These combiners for two or three transmitters were
conceived to couple two or three transmitting frequencies on one antenna. Besides the
power restriction due to the type of cavity that is used, the diplexers and triplexers are
also limited by the frequency range. The distance between the various frequencies must be
greater than 3 MHz. The triplexers must be factory tuned.

limitados da el alcance de potencia. La distancia entre las varias frecuencias debe ser
más de 3 MHz. Los triplexores deben ser sintonizados en la fábrica.
