Overview: 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.
