Directional beacon
A directional radio beacon is a special type of radio beacon with the help of which it is possible to enable a guide of a sea vehicle to access a port or through a strait , e.g. B. in poor weather or in the dark. Due to the universal spread of radar technology , directional radio beacons are now less important and rarely encountered.
function
A directional radio beacon consists of two transmitters on different frequencies, whose identification in Morse code is selected so that a continuous tone can be heard if both transmitters are equally strong. If the operator of the vessel deviates from this line, he hears the Morse code of one or the other transmitter, depending on which side he deviates. He can then steer to port or starboard to reach the ideal line on which the continuous tone can be heard. The transmitter locations must be placed in such a way that the area of the same field strength coincides with the fairway.
Examples
A directional radio beacon existed in Mukran on Rügen, but was made superfluous by modern ship radar systems and switched off around 1974.
