Find them in the Streaming Channels area. None of the Roku stand-alone models have inputs; only outputs. Even the ones with the analog outputs do not have inputs. I have the Roku Express+ 3910X, with analog outputs and there is no built-in OTA tuner. However RokuTVs have a built-in digital OTA television tuner, and those are the only Rokus to have it because Roku never made the sets themselves; they co-manufactured with actual TV manufactuers. TCL was the first TV company to manufacture RokuTV sets. Eventually other companies started manufacturing them as well. Today, the other manufacturers of RokuTV sets include Sharp (previously licensed to Hisense from 2015-2019), Hisense, RCA/ProScan (licensed to Curtis International), Onn (Walmart house brand), Insignia (Best Buy house brand), JVC (manufactured by MTC of Shenzhen, China, licensed to California based JMC Electronics LLC in the US), Westinghouse etc.

I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
