    "comment": "The GPS antemma is mounted to the top of the\r\nSuurupi lighthouse. The description is\r\nfollowing: there is two metal plates - upper\r\nand lower, both 10 mm thick. The lower metal\r\nplate is bolted and welded to the upper part\r\nof the cupola of the lighthouse. Three vertical\r\ntubes are welded to the plate, connecting two\r\nmetal plates (upper and lower). Punched metal\r\npieces are welded to the tubes supporting an\r\nupper plate.  The upper metal plate is bolted\r\nto the metal pieces. Also a metal ladder is\r\nconnected to the upper plate. The upper metal\r\nplate has holes for fixing the tripod. The ends\r\nof the tripod were threaded, which made it\r\npossible to screw the tripod to the platform\r\nwith female screws. The tripod was provided\r\nalso with lift screws to ensure the horizontal\r\nposition of the antenna. The upper part of the\r\ntripod consists of a triangular metal plate\r\nwith a hole in the middle for the bolting of\r\nthe antenna.\r\nThe height of the monument is above the local\r\nground plane.",
