Antenna definition files are required for RET controllers to achieve accurate configurations and communication with antennas in a RET system. This file tells the RET system the tilt range for a given antenna and enables the system to set the tilt angle for the antenna. CommScope provides the most up-to-date antenna definition files for our RET compatible antennas to be managed in the RET systems shown below. It is highly important to download and use the latest antenna definition file to ensure quality electrical tilt adjustment results.

PLEASE NOTE: The antenna definition file is included with download bundles for rack mount controllers.

The latest antenna definition file version is _065, as of 6/23/17.
