Regulation:23Heading:Siting of radar installationVersion Date:30/06/1997

(1) The antenna unit of the radar installation shall be sited so that satisfactory overall performance is achieved in relation to-

        (a) the avoidance of shadow sectors;
        (b) the avoidance of false echoes caused by reflections from the ship's structure; and
        (c) the effect of antenna height on the amplitude and extent of sea-clutter.
(2) The radar display shall be sited on the bridge from which the ship is normally navigated. The siting of one of the displays shall be such that-
        (a) an observer, when viewing the display, faces forward and is readily able to maintain visual look-out;
        (b) there is sufficient space for 2 observers to view the display simultaneously.
(3) The radar installation shall, where practicable, be mounted so as to prevent the performance and reliability of the installation being adversely affected by vibration and so that the installation will not, whilst in service, normally be subject to greater vibration than that specified in the "General Requirements for Marine Navigational Equipment, 1982", issued by the Department of Transport.
