Antenna tags are an object widget representing a springy series of vertices rendered with a bitmap texture which can be attached to object markers. They are only used on the Warthog and Scorpion vehicles, but during Halo's development they were also present on the Spartan (cyborg) biped.

Limits

The game state has limited space for simulated antennas (12 in legacy, 24 in H1A). Extra antennas in the map will not be rendered.
