I am pretty sure almost any LCD TV bought in the last 5 years will have a digital tuner.
Again, or
no tuner. I know this is off-topic, but I thought I should share a bit more on that point, since it might not be obvious why someone would want to buy a television without a tuner.
Tuners are not cheap. They're one of the parts of the television that are a significant source of cost. So if you buy a television with a tuner, and you don't actually use the tuner (I'm guilty), then you're essentially wasting money. To be fair, you're not wasting
too much money. Even though tuners are costly, you don't save
that much money buying a monitor.
Like I said, I'm guilty. I have FiOS TV service, hooked into my TiVo. Then the TiVo is connected to my television, via an HDMI connection. If you're using an HDMI connection (or the yellow video connection, or the black s-video connection, or the red/green/blew component video connection) to get the video to your television, you're not using your tuner in your television. Only that round, typically-screw-on coaxial cable connection feeds signal into your television's tuner.
In my case, I'm using the tuner that's in my TiVo. If you have a DVR, you're probably just using the tuner in the DVR, not the tuner in your television.
In the OP's case, you need the tuner -- absolutely. Rabbit ears, over-the-air reception -- definitely need the tuner. And that's increasingly going to be the
only case when you're going to make use of the tuner in your television. Already, satellite services require you to use the tuner in their receivers and DVRs, instead of the one in your television, and that's either already the case for most levels of service for most cable companies or they've got plans already in motion to make it the case within the next year or two, though in the case of cable companies, there is another option: CableCARD. Very very few televisions, though, are CableCARD-capable, and you will pay extra for that capability.
All you need to do is get an antenna and plug it into the television.
Please keep in mind, though, that not just any ol' antenna will necessarily work for you. That link I posted above is intended to help you (1) figure out what kind of antenna you need, and (2) help you understand what channels you'll be able to tune in with that antenna.
