Used for power division and signal distribution applications. The broad array of splits facilitates balanced signal distribution in
the most comprehensive systems. Additionally, the Tri-Band products allow multi-band signal distribution via a single transmission line
where multi-agency communication systems are required. 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 above the desired coupling value.
