Sold through Crowd Supply rather than the maker’s own shop.

Radio equipment needs certification where you live (FCC, CE, UKCA, ISED, Anatel). Some devices are uncertified or restricted in Brazil. Buyers are responsible for their local law.

Bring along: An SDR receiver, a feed for your band, and somewhere outdoors to point it.
Keep in mind: The dish and the feed are priced separately; receive only.

What’s inside

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.

Research 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.

What still needs checking

Crowd Supply project pages describe the campaign rather than a datasheet; dimensions, weight and full electrical specifications are often absent.
