No. There is no TV tuner card. The ATI Xclaim TV box actually refers to it as an "External TV Tuner". Plus, I don't remember seeing any remarks about a TV tuner card in all the documents. If a Beige G3 came with the "Wings" personality card, which provided audio and video I/O, one could send the signal from the Xclaim TV through these RCA ports. No other card necessary. However, I think it required an ATI graphics accelerator card be present, as the built-in cards either weren't powerful enough, or didn't have enough VRAM.
