Antennae of Triangulation are magical items from the Spelljammer campaign setting, and are usually accompanied by a helmet of liaison.[1][2]
Description[]
Antennae of triangulation are between 20 and 70 feet[3] (6 - 21 meters) long, and resemble the antennae of some gigantic insect. A pair of antennae are accompanied by a helmet of liaison when first created.
Powers[]
Antennae of triangulation are mounted in pairs and are designed to locate the position of any object greater than 8 feet (2.4 meters) across within a 10,000 yard (9,144 meter) radius. The antennae are accompanied by a helmet of liaison which links its wearer directly with the antennae of triangulation, relaying a three dimensional tactical display of nearby wildspace in the mind of the wearer.
When the helmet is put on, the wearer immediately gains a 360° mental picture of the space around their ship. The relative position of all objects within the area change as and when the ship's heading changes, or if the objects in sight change. The antennae make it impossible to surprise the ship, as long as someone is wearing the helmet. Using the helmet and the antennae is as strenuous as powering a helm and requires full rest to recover from the fatigue.
History[]
The antennae of triangulation, and the accompanying helmet of liaison, were designed for use on the Tsunami, the capitol ships of the groundling nation of Wa from Toril. The antennae are mounted on the head of the giant centipede-like vessel, while the helmet is worn by the officer in command, usually the admiral.[3]
