TOOL FOR MEASURING THE AZIMUTH ANGLE OF AN ANTENNA

摘要

1. Tool (1) for the measurement of the elevation angle of a volume antenna for Hertzian waves, of the type comprising a pendulum weight mounted on the antenna (2) and read off means for the stable position of the pendulum to permit the measurement of the angle of elevation of the antenna (2), characterized in that the pendulum is formed by a ball rolling on a concave portion of the antenna (2) and in that the read off means comprises a series of graduations engraved into the concave portion of the antenna.
