Depends on if its just a TV tuner card, or TV/FM Tuner Capture card (which i have)
Most i\'ve seen use coax for the aerial
Capture normally has S-video/Composite input. Either mono/stereo input or passthrough for sound or use your soundcard for stereo sound. Input for remote if you have one with it.
Whatever cables u need for the TV tuner you\'d most likely get with it.
