TX/RX's 85-58 series, 350 – 520 MHzhybrid directional couplers for power division and signal distribution applications.The broad array of splits facilitates balanced signal distribution in the most comprehensive systems.They largely eliminate the near-far problem and maximize the cost-efficiency of the signal boosters.Bi-directional nature of the couplers allows them to be used for two-way communications with minimal loss abovethe desired coupling value.
