The CommScope ATM200-A20 Teletilt RET actuator enables operators to remotely change the electrical downtilt of an antenna. It is shipped in AISG 2.0 mode; however, in the field the actuator can be set to AISG 1.1 or 2.0. as needed. The actuator's absolute position sensor eliminates the need for calibration, enhances precision and prevents dropped calls caused by calibration sweeps. Male and Female AISG connectors facilitate daisy chaining actuators. As many as 32 actuators can be attached to a single control line. This actuator is equipped with a flashing LED, which indicates data transfer and tilt movements. It comes in a weather resistant gasket-sealed container that has a drain hole to permit drainage of condensed moisture.
