The Mobri S-4 is designed to be mounted in the rigging of sailboats. It can be mounted as a semi-permanent installation, or hoisted into the rigging as needed. With its larger reflective area compared to the S-2, this model is well suited for offshore use.
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 4 m/13 ft is recommeded. It should be mounted in the shrouds away from the "shadow" of the mast.
Mounting eyes are moulded in the structure at top and bottom. Durable lashing materials should be used to attach it to the standing rigging.
