For a radar reflector to be as effective as possible, two things should be considered when mounting:
1. Install the radar reflector high up.
On a sailing yacht, mount on the mast top or the uppermost spreader. This ensures that the ship still reflects a sufficient radar echo even if the hull or rig is below the radar horizon.
2. Fix the radar reflector securely.
Mount the radar as securely as possible so that it cannot slip or twist. This avoids non-steady echoes, which can occur when mounted in an overhung position on halyards or the backstay. Non-steady echoes appear and disappear alternately on a radar receiver screen. However, raster scan systems may suppress such signals so that they are not detected with your ship.
