- A Ramark is a radar beacon that may be regarded as a “Radar light house” because it works continuously, whether any ship nearby or not.
- It’s name derived from Radar marker.
- It transmits signals in all directions, covering the entire marine Radar bond (9200 to 9500 MHz if the Ramark is of the X band and 2900 to 3100 MHz if the S band).
- When the own ship’s radar scanner points to the Ramark beacon, signals of the Ramark are received and painted as a series of dots.
- It gives only the Bearing, Not the range.
