Smart Bias Tee - ANT Side/Top of the Tower

The Kaelus SBT0003 provides a flexible Smart Bias Tee solution allowing for AISG and DC to be placed onto a feeder at the bottom of the tower or extracted from the feeder at the top. Operating across all the cellular frequency bands, the SBT0003 provides the following additional benefits.

FEATURES

  • 555-3800MHz operation provides coverage in 600MHz through 3.5GHz frequency bands
  • Available in top of the tower or bottom of the tower applications
  • Primary surge protection limits the voltage let-through from the feeder to the DC port
  • Multiple connector configurations to allow for different installation scenarios
  • IP67 for continuous outdoor operation
