FM Starpoint Diplexers & Triplexers

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.

Estos combinadores para dos o tres tranmisores fueron concebidos para acoplar dos o tres frecuencias en una antena. Además de la restricción de potencia debido al tipo de cavidad usada, los diplexores y triplexores son también 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.
