DIPLEXER 700/850

Designed to combine the North American 700MHz and 850MHz bands the Kaelus DBC0056 provides a compact combining solution with low insertion loss thereby saving main feeder or cable runs.


  • Combines uplink and downlinks of both 700 and 850 bands to one feeder
  • Very low insertion loss
  • Designed for Low IMD
  • Wall or pole mounting
  • Field configurable DC/AISG path
