Whether just to add interest to a tabletop, on the roof of a 28mm building or outside a 6mm command post, or as an objective marker for a mission, antennae are a great addition to any sci-fi terrain collection.
 
This antenna is made from laser-cut card on a single small sheet, with all the parts you need to make one antenna.  The item comes unassembled.  PVA (white) glue or cyanoacrylate (CA/super) glue is recommended for assembly.  This item is not recommended to children below the age of 6 due to small parts.  Older children may require adult supervision.
