TV-less TV tuner? Anyone know of one?

I'm in the Army, so I'm always on the move (unless I'm standing in place for a really long time; such as waiting for equipment, or injections, inspection, I'm told to wait for something else, or I'm doing nothing but my sergeant wants me to look busy). However, I really miss my TV shows. Is there some kind of a TV tuner that allows me to watch television on my laptop without having a cable connected from a cable service?
I looked at the slingbox, and unless I'm misunderstanding, the box needs to be plugged into a wall jack at all times. How can I take it wherever I go if it needs to be plugged in all the time?
Anyone know of a reliable product in this vein. Oh, and I want to connect it to a laptop, so a USB connection would be appreciated. Thanks. B_R.

 

I've provided a link for you to check out. From what I can tell, this device goes into your USB port, you hook up some rabbit ears, and your watching TV happily The link:http://www.powercolor.com/product_realangel360u_usb.html

I'm not completely sure if your asking for a tuner or on demand TV via the internet. If you're in the military I doubt you would want the local TV channels, but I could be wrong on this one.

 

On demand TV via the internet? I was talking about a tuner, but I'd never heard of this thing. enlighten me please.

Dave, thanks for the Link.:cool
