I have this (link below) that I bought to watch live tv on my computer. Hauppauge also supply a little antenna and a remote control with the usb TV tuner in this kit. Works fine as long as the reception for the TV signal is strong enough for the antenna they have supplied... You can bring it with you anywhere of course, as long as you also have your laptop.
Supports these TV standards:
NTSC Analog Cable, Over the Air TV
ATSC Digital Over the Air HDTV
Clear QAM Digital Cable TV
