Designed to be mounted in the rigging of sailboats. The best performance is achieved when the Mobri radar reflector is mounted in a vertical position as high as possible above the deck, a minimum of 13' is recommended. It should be mounted in the shrouds away from the "shadow" of the mast. Mounting eyes are molded in the structure at top and bottom.
