If performance monitor arm is positioned, within this blanking area, the pedestal must be turned because the radar performance monitor is not working where there is no transmission in the sector of its sensor.
30 kW S-BAND/U ANTENNA GROUP INSTALLATION NOTE The plastic protection cover on the pedestal rotary joint must not be removed until just before mounting the antenna. Anyhow the rotary joint must not be left uncovered when the antenna is not mounted NOTE The fixing materials to fasten the antenna pedestal to the ship’s platform are not provided by the manufacturer.
