QUADRUPLEXER 850/900/1800/2100

Designed to combine 850, 900, 1800 and 2100 technologies, the Kaelus QBC0009 saves significant capital and operational expenses by limiting feeder runs, and components needed on the tower. Available in an outdoor package the QBC0009 has the following features:


  • Combines 850, 900, 1800 and 2100 bands
  • Very low insertion loss
  • Designed for low passive intermodulation
  • DC/AISG bypass field settable
  • Wall or pole mounting
  • High power handling

dc / aisg
A field selectable DC/AISG path is achieved via mechanical links on a IEC60130-9, 8-pin female connector (see mechanical diagram). It is Kaelus’s recommendation that due to AISG link budget reasons that a maximum of 2 DC/AISG paths are activated simultaneously without active repeating of the AISG signal
