The Sunsight Antenna Alignment Tool (AAT) provides GPS antenna alignment to within 1 degree of accuracy for azimuth, eliminating re-climbs and site re-visits. The AAT measures, azimuth, tilt, roll and height. Add-on features include a laser tape drop, which measures the exact height, and a azimuth scope kit, which obtains antenna azimuth from the ground. The unit is RF-hardened and shielded for use on live antennas and water-resistant. It mounts to all antenna types. An auto gyro assists with challenging environments. www.sunsight.com
