DBSPECTRA's HC110T1-16F control station combiner, 746 – 869 MHz, 16 channels. Reduce the number of antennas needed with the dbSpectra's control station combiner, a trunked or conventional mobile radio combiner/multicoupler. Connect six mobile radios with our 6-port model and reduce antenna requirements from six to two. Your overall system port-to-port isolation can be increased using this combiner for applications where individual radio antennas do not provide enough spatial RF isolation, thus removing all the guesswork. 3RU.
