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.
All TVs including new ATSC Digital ones use the same frequencies as older NTSC Analog sets. An amplified antenna is recommended because there is a threshold where a weak analog signal will be visible (with considerable static) but a digital tuner will not have sufficient strength to display a digital (no noise or static) picture. Outdoor roof Antennas work great as well, you don't need an HDTV antenna, discount stores should have one for around $30.
Resolution refers to the dots per inch (Dpi) on your monitor. The higher the resolution the better the picture. For instance next time you go shopping check out the HDTV, should say something like 1080X1000 or for laptop monitors it'll say 1024X768 which is the standard for laptops.
If you've been walking through the local electronics store, or browsing HDTVs online (and I'm sure you have), you may have noticed a lot of attention being payed to "120 Hertz," that is, the refresh rate of some newer model televisions. The refresh rate refers to the frequency with which the image on the screen is updated, or re-drawn. "120 Hertz" means that the image you are looking at on the HDTV is updated 120 times a second.
No, you do not need a separate HDTV antenna unless you are using the antenna to get your channels. If you have cable TV, then the antenna is not necessary.
You would need to run the Cable co-ax into a splitter switch, and connect the HDTV antenna to the other side.
It's not uncommon. Look to see if your cable box has an antenna input. If it does, it's just a remote click to change from cable to TV. If not, you'll have to use an antenna switcher.
HDTV, High Definition Source (HD Cable Box, Antenna, HD Satellite Box), the cables to connect them.
You would need a HDTV tuner when you don't have cable. You would need a tuner when you can't get a good reception from the antenna and when you don't have cable.
I could be wrong, but I believe you are talking about an HDMI cable. Between the antenna and the TV set use RG6 cable.
HDTV does require an antenna. However, if you are using an antenna on your existing television there is no need to go out and purchase another. HDTV's do not require a special antenna.
Coaxial cable, RG6u or RG 59u. The RG6u has less loss for longer cable runs.
The cost for HDTV programming will vary in different regions,please contact your cable provider.
You must have a HDTV converter box from your cable company.
HDTV antenna online from Amazon has really great service. They also sell really good prices for HDTV and antenna that would help you since you broke your antenna.
Put up your own Antenna if you have a HDTV or subscribe to a Satellite service.
