Description
A lozenge with horizontal axis 3 3/8 inches (8.57 cm) overall and vertical axis 2 3/4 inches (6.99 cm) overall consisting of four lozenges conjoined, the upper of colonial blue and bearing a white five pointed star and each of the remaining three divided into white and orange areas by a zig-zag partition line, all within a 1/8 inch (.32 cm) buff border.

Symbolism
Orange and white are the colors used by Signal units. Colonial blue and buff were suggested by the flag of the state of Delaware. The single star alludes to Delaware as the "first state" to sign the Constitution; it is also used to indicate the capital city of Dover, the unit's home area. The pattern formed by the conjoined lozenges is indicative of precise planning and represents the unit's capabilities. The white and orange zig-zag simulates electric flashes and refers to the technology of a communications system and the unit's mission.
