depends on your location. If you use antenna run a channel scan. It should allow your TV to find the CW again.
I am replying to your question about the need of a HDTV antenna and where to get one, any electronic stores i.e.: BestBuy, future shop, radio shack, the source if you cannot find it there go to to more of a specialty TV store they are bound to have one.
I am unable to find much information as to whether or not the Apple TV makes an HDTV with an antenna, but from what I have found it is connected through your internet. I believe that you would have to purchase an antenna separate from the TV, but I strongly advise asking a qualified electronics salesperson for the best advise.
No, and actually you will probably get more over the air channels than before, and with much higher quality than you might expect. Some of the channels are being broadcast in HDTV format, which has higher resolution than standard TV. Look at other questions about HDTV and how to find out what stations are in your area and how to choose the best antenna.
One can find information about HDTV at websites like ABCLocal, NHTC, Wikii Answers, Jasco Products, Time Warner Cable, ZD Net and Dennys Antenna Service. Alternate places are How Stuff Works, Televisions How To and HDTV Professor.
You can find a replacement hdtv display for your television on the following site: http://www.thescreenguys.com. They have just about everything.
If you are curious to buy a LG HDTV and you would like to find the cheapest or compare prices and find a good deal, this is a great place to do it. http://www.buyledtelevision.com/LG-42SL90-LED-HDTV
Plan backwards; make sure you have a television with at least 720p, though 1080p is worth the extra price. Connect a TiVo or VCR/DVD-R or a Blu-ray player with upconversion; HDTV/DVD combos are convenient while HDTV/Blu-ray combos are hard to find. An outdoor antenna is ideal, but a bowtie antenna is pretty good if you can elevate it near a window. AntennaTV and THIS network has occasional gems along with secondary PBS stations.
I honestly can't find any benefits. Projection Tv's are hard to find and expensive, while regular HDTv's have come way down in price. A good quality, decent-sized HDTv is less than $1,000. Projection Tv's are large and bulky. HDTv's are thin and sleek.

You’ve probably seen the commercials 100 times, asking you if you’re ready for the switch to DTV, but are you ready? If not, you should have been, because the government made the switch whether you were ready or not. All DTV means is that the government standard for television broadcasting switched from analog to digital. This doesn’t sound like a big deal, except some TVs and TV antennas can’t handle the conversion. So, what do you do? You’ll have to go out and find yourself a new TV antenna that can receive the digital signal. If you’ve never shopped for a TV antenna, don’t worry. It’s not too difficult to procure one. You just need to know where to look and what to look for. There are several types of antennas on the market, but you’re going to want to find one that will help you pull that DTV signal, and not the older, analog signal. Now, you can find HDTV antennas on the market, as opposed to just regular TV antennas. Obviously, these won’t do you any good if you don’t have an HDTV, but you should still be able to get great reception with one, even if you’re in standard definition. Make sure you look for an HDTV antenna when you do your shopping. The next thing you need to decide is if you want an indoor or an outdoor antenna. This is pretty much as easy as it sounds, do you want your antenna to be station indoors or outdoors? Standard TV antennas are station indoors and are attached directly to the TV. Outdoor antennas, though, can be mounted on the roof, with a cable run to the TV you’re trying to get a signal on. While the outdoor antenna may be a little harder to set up, you’re going to get a much better picture than with the standard indoor antenna. The final thing you need to consider is price. With the upgrade in technology, TV antennas have really come down in price. You can find a simple, indoor antenna for as little as $7, but even if you go for the top of the line, you won’t have to spend more than about $60 for a high- quality, outdoor HDTV antenna. So, if you’re having trouble with the DTV signal, you may need to go out and get yourself a new TV antenna. Make sure you check out the HDTV antennas and whether or not you want an indoor or outdoor antenna, and you’ll be all set.
Here's a way to find out. Go to your TV's menu and do a new channel search. If it comes up with channels like channel X.1 (which is usually for HDTV) then tune it in after the TV's done. If you can see it, chances are you have a digital tuner. If you can't, then the answer is that it doesn't.
