## Blueprint

**Closed design.** KrakenRF publishes manuals and a 3D-printable feed adapter/enclosure drawings for Discovery Dish, but no electrical schematic for the active filtered feed.

_Notes:_ Discovery Dish is described by the maker as an antenna with an active filtered feed (no MCU/display). The discoverydish_docs GitHub repo (its official wiki-linked docs repo) has full manuals, a 3D-printable adapter, and enclosure drawings, but no schematic for the feed's active filter/LNA circuitry was found, so electronics remain closed. No specific IC part numbers for the feed are disclosed by KrakenRF.
