Stambha is a Progenitor component is a Deep Space Broadcast antenna, configured to fit a frigate-sized vessel.
This Progenitor communications antenna differs from most others used by Progenitor objects due to the difference in materials used in its construction. Though the exact composition is unknown, this Deep Space Phased Antenna can handle traffic of an entire planetary system without difficulty. They are widely sought after by collectors and salvagers wishing to use such powerful antenna.
Because of their unique materials construction, the Stambha are regarded as nearly indestructible and capable of great, passive feats. Since they are attuned to certain radiation frequencies, one use for them in ancient Yaot history was a a kind of dowsing rod to locate active Progenitor relics. It is thought a Stambha allowed the early Yaot to find their first caches of lost Progenitor equipment, giving them an edge over their neighbors, the Tanoch. Stambhas were likely used to locate the Five Pillars bordering space with the Tanoch Empire.
Because every Stambha is attuned slightly differently, it is believed by the Yaot that each Stambha can locate specific objects, and each is to be prized. The Yaot have gone to great lengths to acquire them when they are found.
