Custom Piece – Antenna 1 x 4 / Flagpole (Blue) – 3D Print for LEGO Minifigure

Antenna 1 x 4 / Flagpole (Blue) This is a standard Blue LEGO accessory (Antenna 1 x 4). It consists of a hollow, stud-compatible base (which allows it to click onto any LEGO brick) and extends into a long, smooth vertical shaft with a rounded tip.

Background: This piece is incredibly common in LEGO City and Classic Space themes. While it works perfectly as a Flagpole for castles or government buildings, the blue color makes it especially popular as a Radio Antenna or Communication Aerial on police cars, helicopters, and space rovers. Builders also use it creatively as laser cannons, lever handles, or decorative piping in industrial MOCs (My Own Creations).
