Designed to combine 700, 850, 1900 and AWS technologies, the Kaelus QBC0002 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 electrical block 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
Passband 0 - 3MHz
Insertion loss, single DC/AISG pass 1dB maximum
Return loss, single DC/AISG pass 12dB maximum
Insertion loss, two DC/AISG pass 4.5dB typical
Return loss, two DC/AISG pass 9dB typical
