The intersecting quatrefoil, rays and saltire represent a radio beam and reflect aspects of the unit's mission. Red, black and silver, the former colors of Germany's national flag, allude to service in the Rhineland during World War II. Red and white are also the colors for the signal flags in the branch insignia.
