85-38 Series

85-38 Series, 132-174 MHz, Hybrid Directional Couplers 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.

  • Alodine Gold finish
  • Silver plated N female connectors with gold plated pins
  • Multiple load configurations (no load, 5W, or 25W) available for different power requirements
