An antenna attitude measuring system includes internal and external electrical components providing data for recording and displaying on a handheld device. The data can be transmitted to a database for access by a network operator. The antenna attitude can be adjusted for maximizing telecommunications network performance. The system includes an AISG compliant tilt sensor system mounted in-line between a telecommunications antenna enclosure and a communications cable, and positioned to measure the elevation tilt and slant of a telecommunications antenna enclosure relative to a reference axis. The system includes the ability to connect to and remotely control a plurality of remote electrical tilt control units through only a single connection.
