QUADRUPLEXER 700-900/1800/2100/2600

Designed to combine 700-850-900, 1800, 2100 and 2600 technologies, the Kaelus QBC0003 saves significant capital and operational expenses by limiting feeder runs and components needed on the tower.


  • Combines 700, 850, 1900 and AWS Bands
  • DC/AISG bypass field settable
  • Very low insertion loss
  • Wall or pole mounting
  • Designed for low Passive intermodulation
  • 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.
