ACU-A20-S
Optimizer RT® Antenna Control Unit AISG 2.0

Rev : C | Rev date : 17 Sep 2021
  • The ACU-A20-S Antenna Control Unit (ACU) is part of the complete RFS AISG compliant Optimizer RT® remote antenna control system. The ACU-A20-S is a direct replacement for the ACU-A20-N. With its smaller and more ergonomic form factor, installation is easier and more cost-effective especially when using multi-band antennas with several ACUs.
  • The Optimizer RT® remote antenna control system permits accurate antenna tilt operations to be conducted - without riggers or crane equipment - either from the tower base or the network management center.

FEATURES / BENEFITS

  • Compliant with AISG standards
  • Enables remote electrical tilt of antennas
  • Direct replacement for the ACU-A20-N in a smaller size
  • Travel time <30 seconds typically
