Sorry, no overhead (portable) projector has a front end (tuner) built in. That would also require speakers. The primary advantage of the portable projector is size. Adding a tuner and speakers would be like going backwards. Just use a cable box, and take the highest quality signal available and run it into your projector’s input.
HDMI/DVI, Component, S-Video, or composite video, sequentially best to worst.
