Radar sets for small boats

There's not much to see of these radars. They are hidden under a cylindrical radome, which can have a diameter of up to two feets. They are mounted as high up as possible on the mast of sailing boats or the roof of motor yachts to reduce the influence of the earth's curvature on the range. Older radar devices still use a magnetron with a pulse power of up to 4 kW. Newer radar sets use the FMCW principle with a transmitting power of less than one watt.

(Radar sets with beam antennas are included in the category there.)
